问题 Hi I am trying to write a java client for secure hbase. I want to do kinit also from code itself for that i`m using the usergroup information class. Can anyone point out where am I going wrong here? this is the main method that Im trying to connect o hbase from. I have to add the configuration in the CONfiguration object rather than using the xml, because the client can be located anywhere. Please see the code below: public static void main(String [] args) { try { System.setProperty

Hadoop mapreduce streaming from HBase

由 自作多情 提交于 2019-12-18 16:55:39
问题 I'm building a Hadoop (0.20.1) mapreduce job that uses HBase (0.20.1) as both the data source and data sink. I would like to write the job in Python which has required me to use hadoop-0.20.1-streaming.jar to stream data to and from my Python scripts. This works fine if the data source/sink are HDFS files. Does Hadoop support streaming from/to HBase for mapreduce? 回答1: This seems to do what I want but it's not part of the Hadoop distribution. Any other suggestions or comments still welcome.

What exactly is the zookeeper quorum setting in hbase-site.xml?

由 一个人想着一个人 提交于 2019-12-18 14:09:28
问题 What exactly is the zookeeper quorum setting in hbase-site.xml? 回答1: As described in hbase-default.xml, here's the setting: Comma separated list of servers in the ZooKeeper Quorum. For example, "host1.mydomain.com,host2.mydomain.com,host3.mydomain.com". By default this is set to localhost for local and pseudo-distributed modes of operation. For a fully-distributed setup, this should be set to a full list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in hbase-env.sh this is the list
