…_HOME/etc to config [TRAFODION-2653] Sort operator loops at times All HBase client connections from Trafodion uses Trafodion configuration concept. Any client side property can now be set in trafodion-site.xml. The scratch files are now open in blocking mode. Hence any scratch file operation shouldn't return EAGAIN. The internal table TDDL of table is now created without any table coprocessors attached to it.

There was a problem hiding this comment.
Why thread.sleep if IO exception?
There was a problem hiding this comment.
This is to stagger the sync operation assuming that it is colliding with another thread doing sync. It was thought that was the cause for concurrentModificationException at the time of sync. But @shangshengtung came up with different change that took care of concurrentModificationException. He will be delivering his change in a separate PR soon
[TRAFODION-2653] Sort operator loops at times
All HBase client connections from Trafodion uses Trafodion configuration concept. Any client side property can now be set in trafodion-site.xml.
The scratch files are now open in blocking mode. Hence any scratch file operation shouldn't return EAGAIN.
The internal table TDDL of table is now created without any table co-processors attached to it
The WAL sync can now be synchronized if needed to avoid DWE
