[jira] [Updated] (HBASE-14712) MasterProcWALs never clean up

     [ https://issues.apache.org/jira/browse/HBASE-14712?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matteo Bertozzi updated HBASE-14712:
------------------------------------
    Attachment: HBASE-14712-v1.patch

v1 is a more extensive fix. has the v0 periodic cleanup + some fix to the tracker. This should do the trick under normal behavior.
there are other things as TODO since the first patch, that will always maintain a low and short number of wals, but i'm going to do that later in another jiras.

> MasterProcWALs directory grows pretty much un-bounded. Because of that when master failover happens the NN is flooded with connections and everything grinds to a halt.
