Hi All
I have a query regarding Hbase replication and OldWals
Hbase version 1.2.1
To enable Hbase indexing we use below command on table
alter '<NameOfTable>', {NAME => 'CF1', REPLICATION_SCOPE => 1}
By Doing this actually replication get enabled as hbase-indexer required
it, as per my understanding indexer use hbase WAL (Please correct me if I
am wrong).
so question is How Hbase syncronize with Solr Indexer? What is the role of
replication? what optimization we can apply in order to reduce data size?
I can see that our OldWals are getting filled , if Hmaster it self taking
care why it's reached to 7.2 TB? what if I delete it, does it impact solr
indexing?
7.2 K 21.5 K /hbase/.hbase-snapshot
0 0 /hbase/.tmp
0 0 /hbase/MasterProcWALs
18.3 G 60.2 G /hbase/WALs
28.7 G 86.1 G /hbase/archive
0 0 /hbase/corrupt
1.7 T 5.2 T /hbase/data
42 126 /hbase/hbase.id
7 21 /hbase/hbase.version
7.2 T 21.6 T /hbase/oldWALs
Thanks
