> Minor annoyance, when starting a master I very often get 1 or more stack traces like
these:
> {quote}
> 2011-11-02 00:39:14,448 INFO org.apache.hadoop.hbase.catalog.CatalogTracker: Retrying
> org.apache.hadoop.hbase.NotAllMetaRegionsOnlineException: Timed out (100ms)
> 	at org.apache.hadoop.hbase.catalog.CatalogTracker.waitForMeta(CatalogTracker.java:449)
> 	at org.apache.hadoop.hbase.catalog.CatalogTracker.waitForMeta(CatalogTracker.java:413)
> 	at org.apache.hadoop.hbase.master.HMaster.assignRootAndMeta(HMaster.java:541)
> 	at org.apache.hadoop.hbase.master.HMaster.finishInitialization(HMaster.java:468)
> 	at org.apache.hadoop.hbase.master.HMaster.run(HMaster.java:309)

> {quote}
> 1) it's not super clear what's going on (putting myself in a new user's head) and 2)
those exceptions look bad (until you see they are at INFO level).
> I'd just do a little cleanup: remove the stack trace, add a more meaningful message.
