I'm new to hadoop.
I have installed my hbase setup using Cloudera (normal installation) on 5 servers. I created some table and filled some data.
Now I monitored the hdfs folder sizes. I can see that the data node is keeping giving consistent reading. But my namenode and journal node disk usage in increasing each time I check.
Though I have a small amount of data, the journal node and name nodes are increasing by 30MB(approx) / day.
Am I missing something in the configurations?
And after some research i found out the issue, why the edit logs are not cleared. Its a setting in hadoop.
*dfs.namenode.num.extra.edits.retained = 1000000.
This is the default value set . Reference
