Wei Zhou updated HDFS-10885:
----------------------------
Attachment: HDFS-10885-HDFS-10285.06.patch
Thanks [~rakeshr] and [~umamaheswararao] for the comments! The patch is updated
accroding to the suggestions but with some differences:
1. RPC call {{isStoragePolicySatisfierActive()}} added for client to identify
the status of SPS, it returns only a bool value.
{quote}
After the startup, should do a double check ensuring that there is no lease
exists. If lease exists, then stop SPS.
{quote}
2. Currenly not implemented as the startup stage is not a time consuming
procedure.
3. On Mover side, code of processes like connecting to NN and creating ID file
are shared by many modules, it's inconvenient to modify the code to add checks
that special for Mover. So I only check the status of SPS just before move
operation, suppose this should not bring in logical bugs. What's your opinion?
Thanks!
