Summary: 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. When using
public void batch(List<? extends Row> actions, Object[] results)
got
java.lang.reflect.InvocationTargetException
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

at org.apache.hadoop.hbase.client.HTable.batch(HTable.java:1000)
Interestingly no exception is thrown when using the deprecated method
public Object[] batch(List<? extends Row> actions)
This is a sample code in Scala:
val table = connection.getTable(TableName.valueOf("test_table"))
val increments = for (i <- 0 until 10000) yield {
val rand = Random.nextDouble().toString
val increment = new Increment(rand.getBytes)
increment.addColumn(family, qualifier, Random.nextLong())
increment
}
table.batch(increments, Array.empty[Object])
