max number of open files when testing HBase on the Jenkins server
Hello,

I saw this error when testing my patch on Jenkins:

Caused by: java.io.IOException: Too many open files
at sun.nio.ch.IOUtil.initPipe(Native Method)
at sun.nio.ch.EPollSelectorImpl.<init>(EPollSelectorImpl.java:49)

(Full log: https://builds.apache.org/job/PreCommit-HBASE-Build/364//testReport/org.apache.hadoop.hbase.client/TestAdmin/testCheckHBaseAvailableClosesConnection/)

I am not sure who maintains the Jenkins server, but it would be nice to
increase the maximum number of open files for HBase unit tests.

Thanks,
--Mikhail
