stack updated HBASE-15386:
--------------------------
Resolution: Fixed
Fix Version/s: 1.2.2
1.4.0
1.3.0
2.0.0
Release Note:
This was a non-issue. The PREFETCH_... flag actually works. While here though
made the following additions.
Changes the prefetch TRACE-level loggings to include the word 'Prefetch' in
them so you know what they are about.
Changes the cryptic logging of the CacheConfig#toString to have some preamble
saying why and what column family is responsible (helps figure what is going on)
Add test that verifies setting flag on HColumnDescriptor actually works.
Status: Resolved (was: Patch Available)
> PREFETCH_BLOCKS_ON_OPEN in HColumnDescriptor is ignored
