[jira] [Updated] (HIVE-18212) Make sure Yetus check always has a full log

["Adam Szita (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-18212?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Adam Szita updated HIVE-18212:
------------------------------
    Description: 
Some yetus log files are left incomplete, and in these same runs {{tee}} subprocesses are left running and dangling on the ptest server.
This is because of a bug in the yetus runner velocity template script where we make a redirection of stdout:
{code}
./dev-support/test-patch.sh ${patchFile} ..... 2>&1 | tee ${logFile}
{code}
If the yetus output is big enough (>62K) tee will stop writing the log file and is left running even after {{test-patch.sh}} finished successfully. This because we don't make anything consume the stdout and most probably some buffers get full on Linux side.

We should also make sure that yetus runs(since they are executed parallel to ptest test phase) are not interfering with each other in case they run very long and overlap.
