Hi,
I am getting following Kryo deserialization error when trying to buklload
Cached RDD into Hbase. It works if I don't cache the RDD. I cache it
with MEMORY_ONLY_SER.
here's the code snippet:
hbaseRdd.values.foreachPartition{ itr =>
val hConf = HBaseConfiguration.create()
hConf.setInt("hbase.client.write.buffer", 16097152)
val table = new HTable(hConf, tableName)
itr.grouped(100).foreach(table.put(_))
table.close()
}
hbaseRdd is of type RDD[(ImmutableBytesWritable, Put)]
Exception I am getting. I read on Kryo JIRA that this may be issue with
incorrect use of serialization library. So could this be issue with
twitter-chill library or spark core it self ?
