Ted Yu commented on HBASE-18541:

I used the 'for' command which reproduced the test failure.
However, there was not much information in the test output:
-rw-r--r-- 1 root root 10 Aug  9 17:59 exitCode
-rw-r--r-- 1 root root 15 Aug  9 17:59 output
-rw-r--r-- 1 root root  0 Aug  9 17:59 results

> retry-test and multi-retry-test fails flakily when run with 
> {code}
> buck test --all --no-results-cache
> {code}
> or when run in a loop:
> {code}
> for i in `seq 1 10`; do buck test --no-results-cache core:retry-test || break 
> 1; done
> {code}
> The problem seems to be within the JNI internals and usually happens at the 
> create table method call. I was not able to inspect much, but the comments in 
> our mini-cluster indicate that we may need to use global references instead 
> of local ones. I suspect the problem happens when there is a GC run for the 
> test since the failure happens usually after some time (but almost always in 
> create table method). 
> [~ted_yu] do you mind taking a look at this.
