[~stack] Oh, is this a jenkins config? In HBASE-12953 I modified pom.xml in patch v4 and seems
TestDistributedLogSplitting passed.

instead of 1000ms, this is likely due to a long garbage collecting pause and it's usually
bad, see http://hbase.apache.org/book.html#trouble.rs.runtime.zkexpired

> Maybe we should increase the max heap size since this test starts 6 regionservers.
