bq. HBase scan operation like scan StartROW and EndROW in RDD?
I don't think RDD supports concept of start row and end row.
In HBase, please take a look at the following methods of Scan:
public Scan setStartRow(byte [] startRow) {
public Scan setStopRow(byte [] stopRow) {
Cheers
On Sun,
I am already using STRATROW and ENDROW in Hbase from newAPIHadoopRDD.
Can I do similar with RDD?.lets say use Filter in RDD to get only those
records which matches the same Criteria mentioned in STARTROW and Stop
ROW.will it much faster than Hbase querying?

You do need to apply the patch since 0.96 doesn't have this feature.
For JavaSparkContext.newAPIHadoopRDD, can you check region server metrics
to see where the overhead might be (compared to creating scan and firing
query using native client) ?
Thanks

Sure I will check.

Looks like MultiRowRangeFilter would serve your need.
See HBASE-11144.
HBase 1.1 would be released in May.
You can also backport it to the HBase release you're using.

by using below code i can get result for one STARTROW and ENDROW.

Hi All,
Can we get the result of the multiple scan
from JavaSparkContext.newAPIHadoopRDD from Hbase.
This method first parameter take configuration object where I have added
filter. but how Can I query multiple scan from same table calling this API
only once?
