sangjiaqi updated HBASE-23650:
------------------------------
Description:
NullPointException occurs when the SnapshotCleaner calls the init function to
initialize the HMaster parameter. Similar to the construction method of
HFileCleaner, because the construction method of LogCleaner did not have
HMaster parameter, leading to errors. Therefore, the construction method of
LogCleaner solves the problem by adding HMaster parameters.
The Log:
java.lang.NullPointerException
