Masatake Iwasaki updated HDFS-8463:
-----------------------------------
Attachment: HDFS-8463.001.patch
I think there should be guard because {{seekToNewSource}} is exposed to public
via FSDataInputStream.
I attached 001. It keeps current behaviour and just throws IOException instead
of NullPointerException when {{seekToNewSource}} is called without
pre-condition satisfied.
> Calling DFSInputStream.seekToNewSource just after stream creation causes
> NullPointerException
