Subject OutOfOrderScannerNextException
Date Mon, 07 Sep 2015 10:56:56 GMT
I am using titan which use hbase as it's storage engine. The hbase
version is 1.0.0-cdh5.4.4.
it's a full table scan over a large table. Is there any configuration
I can change to tackle this problem.
The exception stack is:

Exception in thread "main" java.lang.RuntimeException:
org.apache.hadoop.hbase.DoNotRetryIOException: Failed after retry of
OutOfOrderScannerNextException: was there a rpc timeout?
