Lars Hofhansl commented on HBASE-11007:
---------------------------------------
There's TestForceCacheImportantBlocks, which seems to test that... At least in
0.94.
The test exists in trunk, however it looks like the test is not actually
verifying anything anymore. :(
[~stack], [~apurtell], FYI. Looks like the test should either be fixed to
verify something or be removed.
> BLOCKCACHE in schema descriptor seems not aptly named

> Hi,
> It seems that setting BLOCKCACHE key to false will disable the Data blocks
> from being cached but will continue to cache bloom and index blocks. This
> same property seems to be called cacheDataOnRead inside CacheConfig.
> Should this be called CACHE_DATA_ON_READ instead of BLOCKCACHE similar to the
> other CACHE_DATA_ON_WRITE/CACHE_INDEX_ON_WRITE. We got quite confused and
> ended up adding our own property CACHE_DATA_ON_READ - we also added some unit
> tests for the same.
> What do folks think about this ?
> Thanks
