Yu Li commented on HBASE-16960:
-------------------------------
Thanks for checking this [~mantonov]
bq. How bad is this for you? How frequently you see that Yu Li and binlijin?
It's really bad, as mentioned in the JIRA description:
{noformat}
We see regionserver hang when aborting several times and cause all regions on
this regionserver out of service and then all affected applications stop works.
{noformat}
This happens not that frequently but still some, like in our case we saw such
hang before addressing it twice a week or so.
bq. Any follow-ups on that?...
Not yet, but will do. This is another topic and will be big I assume...
bq. Thinking to move it to 1.3.1, where I'd bring those changed and bake in.
Thoughts (that depends on how bad this issue is) ?
I'd suggest to have it in 1.3.0 since it will cause severe problem and with
some frequency. The issue is already reproduced and covered in the UT case here
so it's relatively safe. What's more, we already have this fix running online
here in Alibaba with really high workload for about one week and no regression
issue observed, and I guess this makes it safer to bring in (Smile)? Thanks.
