Manoj Govindassamy updated HDFS-10908:
--------------------------------------
Attachment: HDFS-10908.01.patch
Attaching patch to log BlockReader creation errors.
Since {{BlockReaderRemote#newBlockReader}} throws IOException with information
about the offset issues, logging the IOException should be sufficient to get
the reason for BlockReader creation errors.
{noformat}
throw new IOException("BlockReader: error in first chunk offset (" +
firstChunkOffset + ") startOffset is " +
startOffset + " for file " + file);
{noformat}
> Improve StripedBlockReader#createBlockReader error logging

> In {{StripedBlockReader#createBlockReader}} if any IOException is thrown, the
> error is logged at debug level and then returns a null. This means in a
> typical configuration an NPE may be thrown without logging a cause if the
> StripedBlockReader object is accessed.
