> {{TestAddStripedBlocks}} failed with some editlog corruption. Did some
> debugging, I can see at least two issues:
> # DFSStripedOutputStream tries to send out an empty packet to close the block
> even if writing 0 bytes
> # Because of the above, NN tries to close the file. This exposes another bug
> in {{BlockInfoStriped}}, which writes its data/parity block numbers into the
> close editlog but do not read them while loading.
> This jira aims to only fix #2 and HDFS-8166 is used for fixing #1.
