hbase git commit: HBASE-21000 Default limits for
PressureAwareCompactionThroughputController are too low
Repository: hbase
Updated Branches:
refs/heads/branch-1 ac9401167 -> 1cba67b8b
HBASE-21000 Default limits for PressureAwareCompactionThroughputController are too low
Based on experimental results adjust default pressure-aware compaction
throughput controller settings to bring compaction time with default
settings in line with those measured on branch-1.4 and below.
hbase.hstore.compaction.throughput.lower.bound = 52428800
hbase.hstore.compaction.throughput.higher.bound = 104857600
