      Description

      I have a fairly big table (~100GBs) that, when bootstrapped on current master, fails after a while with:

      This happens always, after a while, and I knew it didn't happen a few weeks ago so I ran git bisect and the culprit is the patch that enables c++ 11. I don't know whether this is a mac only problem or a general problem.

      Git bisect results:

          Enable C++11
          
          This is a rollup of changes necessary to move Kudu to C++11.
          Component changes have been individually reviewed, as follows:
          
          -----------------------------------------------------------------------
          
          Enable Red Hat devtoolset in RHEL 6 Environments
          
          We are moving to C++11 in the near future, and will require a C++11 compatible
          compiler on all suported platforms. Since the RHEL 6 system compiler (GCC 4.4)
          does not support C++11, we need an alternate. The Red Hat devtoolset provides a
          toolchain with GCC 4.9. Libraries (such as libkudu_client.so) which are compiled
          with the Red Hat devtoolset toolchain automatically statically link portions of
          the standard library which are new for C++11. This will allow us to take
          advantage of C++11 features in the client, but still remain compatible with
          stock RHEL 6 systems.
          
          This commit modifies the Jenkins build and test scripts to take advantage of the
          devtoolset toolchain, hides the std library symbols that the devtoolset
          links into library objects, and adds the devtoolset location to the default gcc
          toolchain search paths for the thirdparty LLVM compiler. Additionally, since a
          system compiler which supports C++11 can now be assumed, the precompiled clang
          compiler is no longer a dependency on Linux and has been removed.

          Build thirdparty clang with system compiler
          
          We build LLVM 3.4.2 in thirdparty, but it requires a c++11 compiler to build.
          Now that we require the system compiler to be c++11 compatible, we no longer
          need the bootstrapping compiler.

          Replace boost::unique_lock with std::unique_lock
          
          These particular uses of boost locks were failing to compile on Centos6 because
          the system boost version is buggy when compiling with move semantics.

          Replace boost::shared_lock with kudu::shared_lock in WriteTransaction
          
          The Boost shared_lock implementation distributed with Centos6 does not compile
          with move semantics (specifically the operator= method). std::shared_lock is not
          available till c++14.

          Update thirdparty llvm from 3.4 to 3.7
          
          This updates our thirdparty LLVM version from 3.4 to 3.7. Major changes:
          
          * ASAN and TSAN builds now use the thirdparty clang instead of the bootstrapping
            clang toolchain. The clang toolchain has been removed from the build process.
          * Python 2.7 is now built in thirdparty on systems which have a different system
            Python version. Python 2.7 is a build dependency of LLVM 3.6+.
          * Updated LLVM API calls in the codegen module.

          Build instrumented thirdparty with libstdc++ in TSAN mode
          
          The new c++11 toolchain is more sensitive to TSAN issues in the standard
          library. This commit adds a TSAN instrumented libstdcxx 4.9.3 to the thirdparty
          build when building with TSAN.

          Remove import of macos mach-o/loader.h from gutil/port.h
          
          The llvm/Support/MachO.h header redefines constants as enum variants using the
          same identifier as macro constants declared in the mach-o/loader.h system
          header. This causes issues when macho-o/loader.h is included before the LLVM
          header.
          
          This commit removes the reliance on mach-o/loader.h in gutil/port.h by removing
          some unused macros for working with attribute sections in binaries. The solution
          is not perfect, since the system header may be necessary in the future, but hopefully
          by then a fix will have landed in upstream LLVM
          (https://llvm.org/bugs/show_bug.cgi?id=25871).

          C++11: Simplify thirdparty TSAN build
          
          This commit addresses Adar's feedback on the C++11 patch. TSAN instrumented
          dependencies are now always built on Linux and installed into an alternate
          prefix. This commit will be squashed into the C++11 mega patch prior to
          submission.
          
          The thirdparty directory now includes three prefixes: thirdparty/installed for
          tools and C-only libraries, thirdparty/installed-deps for C++ dependencies, and
          thirdparty/installed-deps-tsan for C++ dependencies for TSAN builds. Keeping the
          prefixes seperate allows us to not require rebuilding thirdparty when switching
          to or from a TSAN instrumented build.
