[jira] [Commented] (HADOOP-8645) Stabilize branch-1-win

    [ https://issues.apache.org/jira/browse/HADOOP-8645?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13863164#comment-13863164 ] 

Dexter Bradshaw commented on HADOOP-8645:
-----------------------------------------

Changes are being reviewed on the HWX JIRA at https://hwxmonarch.atlassian.net/browse/HADOOP. Two outstanding items remain to be completed:

a. TODO: Perform internal hsync on a smaller bounded queue when it approaches capacity approaching capacity.
b. TODO: The I/O queue is single threaded. Mostafa claims that this is for correctness. I have to investigate whether we can in fact do overlapped parallel I/O’s since the addresses of the log blocks are already determined by the streaming interface.

The temporary fix with the unbounded queue is coded and now works with large tables in YCSB.
