You can use google protobuff to call java API frpm c++ , but for this you
must have the Java code which will intract with Hbase.

while I'm still trying to find anything useful in the logs, my question is why
isn't HBase self managing this?
In my 2-3 decades of using databases i had never had to stop a write operation
to do anything such as compactions or whatever. The only time a write would
fail would be if the db runs o
Is there anyway I could attempt to do it?

Is it possible to make a request to region coprocessor endpoints when using
C++ as I would with "org.apache.hadoop.hbase.ipc.CoprocessorRpcChannel" in
Java?

Hi Rajesh,
Not really. In HBase, data is ordered and stored based on the key. If you
want to split by another field, HBase has no clues about the content and
where to nicely split.
So you will run a mapper on HBase splits, and your logic in a reducer...
(Same logic with Spark)

Hi,
I came across MultiTableInputFormat class which convert HBase tabular
data from multiple scanners into a format that is consumable by Map/Reduce.
So what will be the input to the mapper class if I have passed a scan
object to this class which scans two tables. Whether the input to mapper

Hi,
Is there any way to customize hbase input split based on a column value.
For instance if i have a column family 'd' with 'country' column
qualifiers. 'country' column holds value such as USA,Australia,India,China.
So all the rows which holds country value as USA goes to 1 mapper then
Austral
