Jean-Daniel Cryans created HBASE-6841:
-----------------------------------------
Summary: Meta prefetching is slower than doing multiple meta
lookups
Key: HBASE-6841
URL: https://issues.apache.org/jira/browse/HBASE-6841
Project: HBase
Issue Type: Improvement
Reporter: Jean-Daniel Cryans
Priority: Critical
Fix For: 0.94.2
I got myself into a situation where I needed to truncate a massive table while
it was getting hits and surprisingly the clients were not recovering. What I
see in the logs is that every time we prefetch .META. we setup a new
HConnection because we close it on the way out. It's awfully slow.
We should just turn it off or make it useful. jstacks coming up.
