> yarn logs command fails with below error message. Found
> LogAggregationIndexedFileController uses read() to read the contents of
> remoteLog into byte array which sometimes does not read full contents and so
> actual bytes read is not same as offset leading to IOException. readFully()
> can be used.

> Error on loading log meta from
