Micro benchmarks for Apache HDFS/HCFS perf testing. The package includes the following two tests:
FsStress: A very simplistic multi-threaded client that can issue metadata requests to a Apache Hadoop-Compatible File System (HCFS) to measure its metadata IOPS.
WriteFile: A multi-threaded write IO test that allows tweaking write parameters like replication, IO size, number of threads etc. A single thread should be able to saturate the network or single disk bandwidth (whichever is lower).
