Hi Chetan
What do you mean by incremental load from HBase? There is a timestamp
marker for each cell, but not at Row level.

Ted Yu,
You understood wrong, i said Incremental load from HBase to Hive,
individually you can say Incremental Import from HBase.

Hi,
I have a routine in Spark that iterates through Hbase rows and tries to
read columns.
My question is how can I read the correct ordering of columns?
example
val hBaseRDD = sc.newAPIHadoopRDD(conf, classOf[TableInputFormat],
classOf[org.apache.hadoop.hbase.io.ImmutableBytesWritable
Ted Correct, In my case i want Incremental Import from HBASE and
Incremental load to Hive. Both approach discussed earlier with Indexing
seems accurate to me. But like Sqoop support Incremental import and load
for RDBMS, Is there any tool which supports Incremental import from HBase ?

Incremental load traditionally means generating hfiles and
using org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles to load the
data into hbase.
For your use case, the producer needs to find rows where the flag is 0 or 1.
After such rows are obtained, it is up to you how the result of
Ok, Sure will ask.
But what would be generic best practice solution for Incremental load from
HBASE.

I haven't used Gobblin.
You can consider asking Gobblin mailing list of the first option.
The second option would work.

Hello Guys,
I would like to understand different approach for Distributed Incremental
load from HBase, Is there any *tool / incubactor tool* which satisfy
requirement ?
*Approach 1:*
Write Kafka Producer and maintain manually column flag for events and
ingest it with Linkedin Gobblin to HDFS
Thanks , It worked !!

HI All,
I am trying to save data from Spark into HBase using saveHadoopDataSet
API . Please refer the below code . Code is working fine .But the table is
getting stored in the default namespace.how to set the NameSpace in the
below code?
