Jonathan Gray commented on HBASE-1039:
--------------------------------------
Correction from Thibaut on list:
{quote}
You are right. I just saw that that table (the only table) has indeed the
bloomfilters and compression enabled (blockcache is disabled).
{NAME => 'entries', IS_ROOT => 'false', IS_META => 'false', FAMILIES => [{NAME
=> 'data', BLOOMFILTER => 'true', COMPRESSION => 'BLOCK', VERSIONS => '3',
LENGTH => '2147483647', TTL => '-1', IN_MEMORY => 'false', BLOCKCACHE =>
'false'}]}
As for the load/dfs errors, thanks for explaining this. I was only starting up
one region server to have all the log entries at one place, and it was indeed
under heavy load. (Multiple threads setting/getting keys)

He originally said 8 node cluster, but now makes mention of only single
regionserver. So one problem seems related to blooms, probably also seeing
load-related issues.
