Eungsop Yoo commented on HBASE-15055:
-------------------------------------
Without that change, the running for a single test case "testCompactionRatio"
will fail.
I set the value to minsize because it is equal to
HConstants.HREGION_MEMSTORE_FLUSH_SIZE in that test class.
The default value of hbase.hstore.compaction.min.size is set by
HConstants.HREGION_MEMSTORE_FLUSH_SIZE at CompactionConfiguration.
{code}
...
package org.apache.hadoop.hbase.regionserver.compactions;
...
public class CompactionConfiguration {
...
CompactionConfiguration(Configuration conf, StoreConfigInformation
storeConfigInfo) {
...
minCompactSize = conf.getLong(HBASE_HSTORE_COMPACTION_MIN_SIZE_KEY,
storeConfigInfo.getMemstoreFlushSize());
...
{code}
> Major compaction is not triggered when both of TTL and
> hbase.hstore.compaction.max.size are set

> Some large files may be skipped by hbase.hstore.compaction.max.size in
> candidate selection. It causes skipping of major compaction. So the TTL
> expired records are still remained in the disks and keep consuming disks.
> To resolve this issue, I suggest that to skip large files only if there is no
> TTL expired record.
