--------------------------------------
Summary: [0.98] Option for disabling location prefetch
Key: HBASE-11841
URL: https://issues.apache.org/jira/browse/HBASE-11841
Project: HBase
Issue Type: Improvement
Reporter: Andrew Purtell
Assignee: Andrew Purtell
Priority: Minor
Fix For: 0.98.7
On HBASE-10018 we removed location prefetch in versions > 0.98. That issue
enumerates some of the issues with location prefetch. It is already possible to
disable location prefetch on a per table basis via
HTable#setRegionCachePrefetch(TableName tableName, boolean enable) but we
should have a site configuration option that disables prefetch globally without
requiring application code take some special action like setRegionCachePrefetch.
