Re: ANN: The second hbase-0.96-1 release candidate is available for download
-1

I have a new test I tried on 0.96.1rc1. (polishing to share).  Run #2 with
flushes is a correctness regression (HBASE-6195 fixed this in 94, and I had
verified there but it is broken here)..  I'm not sure if #3 (kill) or #4
(kill -9) are a regression against 0.94.   Here's a link to the testcode
(its got all kinds of caveats at the moment and will likely get turn into
integration test).

https://github.com/jmhsieh/hbase/tree/increval

5 nodes
hadoop 2.1.0 (a pre cdh5b1 hdfs).
hbase 0.96.1 rc1

Test: 250000 increments on a single row an single col with various number
of client threads (IncrementBlaster).  Verify we have a count of 250000
after the run (IncrementVerifier).

Run 1: No fault injection.  5 runs.  count = 250000. on multiple runs.
 Correctness verified.  1638 inc/s throughput.
Run 2: flushes table with incrementing row.  count = 246875 !=250000.
 correctness failed.  1517 inc/s throughput.
Run 3: kill of rs hosting incremented row.  count = 243750 != 250000.
Correctness failed.   1451 inc/s throughput.
Run 4: one kill -9 of rs hosting incremented row.  246878.!= 250000.
 Correctness failed. 1395 inc/s (including recovery)
