Uma Maheswara Rao G commented on HDFS-11150:
--------------------------------------------
HI [~yuanbo], Thank you for your efforts. Thank you for adding more test cases.
Here is my suggestion:
I prefer to separate StoragePolicySatsifier changes from here (except safemode
check). We have other JIRAs raised to fix node choosing issues right. Please
use them to fix the issues if you feel any thing. BTW, I have attached a patch
in HDFS-11293. Please check if that is helping to fix these issues. Feel free
to review it and put your feedback there.
Keep only persistence based test cases here. If any other things failing due to
node choosing, add a comment about them, we can fix as part of
HDFS-11293/HDFS-11284.
> [SPS]: Provide persistence when satisfying storage policy.
