I run into the following two issues related to HBase all the time, and therefore am wondering if there are any permanent fixes for these:
1) When I start Hadoop & HBase for the first time, and run a single job it runs successfully; but when I fire 2 (or more) jobs only one of them runs successfully and the other one fails with exception saying... "table system_mappings" doesn't exist. Seems like some type of race condition. How do I bring up HBase with 'system_mappings' table already built? Or, how do I avoid running into this issue? 2) After 30 minutes or so on in-activity, HBase (or may be Zookeeper) stops working. I have to restart it. How do I ensure that it always stays up? Thanks for the help.
