Kevin, from your requirement, I think the 'snapshot' feature with export will work better. Here is some info: http://hbase.apache.org/book/ops.snapshots.html to fully benefit from this feature, you may consider to move to 0.94.6+ I am still curiously about this hard requirement ".. The second map

HBase Replication Progress

Hi, I am having trouble searching for answers regarding HBase replication, so I thought I would email the mailing list. Does HBase provide an API/way to see what has/hasn't been replicated yet? My use case is the following: I run a map reduce job in Cluster A and stick the output in HBase. I wo

2013-11-11 Thread Varun Sharma
I am looking through the code - it seems like HConnectionImplementation keeps rpcTimeout as a class variable. I thought there is a single HConnection object and there is a factory of some Configuration Attributes (including rpc timeout) -> HConnections. Am I missing something - I dint see a threadl

You computer might be swapping, garbaging the memory or another application might be taking the load. And because of that ZK might timeout. If this is a local standalone test server, then there is no real issue of increasing the ZK timeout. JM 2013/11/11 polyimide > No, I haven't been able to

HBase - number of regionserver used

Hi, I have HBase above Hadoop with one master node, one zookeeper node and four regionservers. When I turn up everything, on two nodes (or sometime the same node) are created the tables .META. and -ROOT- and then I create a table called 'usertable' which goes to another random node. Now, when i

Sure! I will have 2 comments. 1) In the documentation, we expect user to have an existing cluster in 0.94 and to try to upgrade it. However, some might prefer to move the data to a new one to not risk the gold data, and migrate the new one. We might want to put some links on DistCP, CopyTable or

No, I haven't been able to resolve this issue. This is a standalone hbase instance backed by local file system. Is this an indication that the load exceeded a single node capacity, a cluster should be used instead? Below are last part of the hbase log and gc log. hbase log -- 2013-1

HBase as a transformation engine

We are looking to use hbase as a transformation engine. In other words, take data already loaded into hbase, run some large calculation/aggregation on that data and then load it back into a rdbms for our BI analytic tools to use. I was curious about what the communities experience is on this and if
