dark_num updated HBASE-24601:
-----------------------------
Description:
The current HBase hfile directory specifies the *HOT* storage strategy by
default(`hbase.hstore.blockingStoreFiles` ), which is different from the
default value of HDFS *heterogeneous* strategy now(should be empty)
It should be set to *NONE* like `hbase.wal.storage.policy`'s default value on
HBASE-20691, and the reason for modification is the same
Otherwise, it could have a significant impact because most HDFS Managers
doesn't know the default value has been changed to *HOT* by hbase, for example:
HDFS manger want to
```
{code:java}
// Set Hbas Hfile dir to ONE_SSD for speed up read
bin/hdfs storagepolicies -setStoragePolicy -path /home/hbase/data -policy
