Eric Yang commented on YARN-9374:
---------------------------------
[~Prabhu Joseph] Thank you for patch 004. "isHBaseDown" method is only by the
test case. Some tests are already detecting IOException instead of using
"isHBaseDown" method. Can we make them similar to use IOException detection,
this helps to remove isHBaseDown method from the main class to minimize code
debris. Thanks

> HBaseTimelineWriterImpl sync writes has to avoid thread blocking if storage
> is down. Currently we check if hbase storage is down in TimelineReader before
> reading entities and fail immediately in YARN-8302. Similar fix is needed for
> write. Async is handled in YARN-9335.
