I pasted code snipped for that method.
here's full def:
def writeRddToHBase2(hbaseRdd: RDD[(ImmutableBytesWritable, Put)],
tableName: String) {
hbaseRdd.values.foreachPartition{ itr =>
val hConf = HBaseConfiguration.create()
hConf.setInt("hbase.client.write.buffer", 16097152)
val table = new HTable(hConf, tableName)
//table.setWriteBufferSize(8388608)
*itr.grouped(100).foreach(table.put(_)) * // << Exception happens
at this point
table.close()
}
}
I am using hbase 0.98.12 mapr distribution.
Thanks
