BE process exits because of failure of loading index #1145
Description
Describe the bug
When loading index of a tablet failed, BE will print a fatal log
fail to load indices. [res=-402 table='xxx.xxxxxxxx']
and then exit.
To Reproduce
This may happen sometimes when tablet's data is broken.
How to resolve
Here are 2 problems:
- Why tablet's data is broken?
- BE should not exit, and should recover from this situation automatically.
We still don't know why a tablet's data is broken. But we can simply set this tablet as bad and report it to FE. FE will repair the bad tablet, so the system will continue to run.
