Description

f I make a fresh clone of the repo, and then run mvn package, I get a test failure:

    -------------------------------------------------------------------------------

    Test set: org.apache.phoenix.schema.PMetaDataImplTest

    -------------------------------------------------------------------------------

    Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.027 sec <<< FAILURE! - in org.apache.phoenix.schema.PMetaDataImplTest

        at org.apache.phoenix.schema.PMetaDataImplTest.testEviction(PMetaDataImplTest.java:98)

This appears to be a bug in PMetaDataImpl.java. The test looks right.

Table b should get evicted first, which creates enough space for d. But in fact c gets evicted first, and then b needs to be evicted as well to make enough room.

I don't know if there's a race condition in here somewhere. It's odd that no one has picked up on a failing test before, so I'm wondering whether it succeeds in some environments. But it fails for me on both Ubuntu and Fedora (both with 64-bit Java 8).
