Hi,
I am using Hbase MultiTableInputFormat to compare 2 tables: Table1 (7
million), Table2 (30 million).
In the driver, i am passing to scans ( without any filters). In my mapper i
am doing a compare and writing the summary in Reducer.
Any settings specific to this scenario that might speed up
I understand that setup and cleanup methods of Mapper/Reducer are called
for each task, so if you have 20 mappers running, the setup / cleanup will
be called for each one.
Is there a setup like method to for the entire mapreduce program. Basically
i want to open only 1 connectionto a HBase
We have a java application (on tomcat) that connects to Hbase. We are getting
the below errors when we stop tomcat. Any thoughts?
SEVERE: The web application [/testapp] appears to have started a thread
named [hbase-tablepool-168-thread-1] but has failed to stop it. This is very
likely to create
Is there any java api to limit the number of scanned records after using
start and stop rows? Is pagefilter an option?
