    [ https://issues.apache.org/jira/browse/HDFS-11694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16010956#comment-16010956

Chen Liang commented on HDFS-11694:
-----------------------------------

Thanks [~msingh] for the updates! v003 patch LGTM, {{TestCBlockCLI}} passed locally, and {{TestDFSUpgradeFromImage}}
is known to be failing consistently. 

Have committed to the feature branch, thanks Mukul for the contribution!

> This bug tracks 2 issues
> 1) The change supports periodic flushing of BlockIdBuffer, earlier this buffer was only
flushed when either the buffer was full or shutdown was triggered
> 2) This change also adds 2 BlockIdBuffer(s), this will ensure that incoming writes are
not blocked on BlockIdBuffer flush.
