Vladimir Rodionov commented on HBASE-15509:
-------------------------------------------
{quote}
HFileContext is meant to be immutable. You add methods that do get/set.
{quote}
Any other way to pass configuration to HFileBlock.Writer?
{quote}
We add new configs for that non-existent 'expert hbase user' to twiddle:
"hbase.hfile.write.buffer-reuse.max.size" The on/off switch is fine but this
new 'sizing' with no means of measuring if an arbitrary setting is improving
things or making them worse.
{quote}
I do not mind if we make default and no config options will be required.
