Subject [jira] Created: (HBASE-1062) Compactions at (re)start on a very large table can overwhelm DFS

Compactions at (re)start on a very large table can overwhelm DFS
----------------------------------------------------------------

                 Key: HBASE-1062
                 URL: https://issues.apache.org/jira/browse/HBASE-1062
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: Andrew Purtell


Given a large table, > 1000 regions for example, if a cluster restart is necessary, the
compactions undertaken by the regionservers when the master makes initial region assignments
can overwhelm DFS, leading to file errors and data loss. This condition is exacerbated if
write load was heavy before restart and so many regions want to split as soon as they are
opened.
