Gergely Novák commented on YARN-5475:
-------------------------------------

This is a permission issue. Some observations:
* testReadAcontainerLogs1 only fails if ran after testForCorruptedAggregatedLogs
* TestAggregatedLogFormat's permissions:
** after testForCorruptedAggregatedLogs: rwxr-xr-x 
** after testReadAcontainerLogs1 (if testForCorruptedAggregatedLogs ran): 
*rw-r-----*
** after testReadAcontainerLogs1 (if testForCorruptedAggregatedLogs did'n run) 
rwxr-xr-x
* removing the line {{fs.mkdirs(subDir);}} from testReadAcontainerLog() seems 
to solve the issue
