Ted Yu commented on HBASE-17680:
--------------------------------
Noticed the following from valgrind output:

{code}
Line 73 is this line:
{code}
rv = JNI_CreateJavaVM(jvm, (void **)&env_, &args);
{code}
Where jvm is JavaVM **jvm
Without symbols from libjvm.so, it is not easy to know what the actual error is.

> Currently tests start local hbase cluster through hbase shell.
> There is less control over the configuration of the local cluster this way.
> This issue would replace hbase shell with JNI interface to mini cluster.
> We would have full control over the cluster behavior.
> Thanks to [~devaraj] who started this initiative.
