Keith Lui commented on HBASE-14988: ----------------------------------- It's not related to the onejar for sure. Same issue happens when running in Apache Spark Streaming which tries to consume data from Kafka and writes to HBase. java.lang.AssertionError: results.length at org.apache.hadoop.hbase.client.AsyncProcess$AsyncRequestFutureImpl.<init>(AsyncProcess.java:763) at org.apache.hadoop.hbase.client.AsyncProcess.createAsyncRequestFuture(AsyncProcess.java:1578) at org.apache.hadoop.hbase.client.AsyncProcess.submitAll(AsyncProcess.java:554) at org.apache.hadoop.hbase.client.HTable.batch(HTable.java:1000) This error will not show up and run smoothly when using the deprecated batch method. In addition, when the number of increments decrease to 1K, it will not run into the same assertion error. So the issue should be related to the new batch method when the numbers of increment is huge. > java.lang.reflect.InvocationTargetException when doing batch with large > number of increment > ------------------------------------------------------------------------------------------- > > Key: HBASE-14988 > URL: https://issues.apache.org/jira/browse/HBASE-14988 > Project: HBase > Issue Type: Bug > Affects Versions: 1.0.0 > Reporter: Keith Lui > > Tried to do a 10K increment with batch.
