Chesnay Schepler commented on FLINK-10609:
------------------------------------------
The 1.6 failure (elasticsearch) doesn't appear to be causing the build failure
(at least locally for me). it's not a new issue and existed at least since 1.4.
The 1.5 issue (hbase) is more concerning. For one the test code is pretty bad
since it casts to log4j loggers to set some log levels, which both (as seen
here) can cause stability issues and also seems simply unnecessary. That said,
the actual logger instance is a {{SLF4JLocationAwareLog }}from from
{{jcl-over-slf4j}}, but this dependency doesn't appear in the dependency tree
of {{flink-hbase}}. So this is pretty weird.
