First, we add test resources to CLASSPATH when tests run. W/o it, there was no logging of hbase-zookeeper test output (not sure why I have to add this here and not over in hbase-server; research turns up nothing so far). M hbase-zookeeper/src/main/java/org/apache/hadoop/hbase/zookeeper/ZKMainServer.java Improve fail log message. M hbase-zookeeper/src/test/java/org/apache/hadoop/hbase/zookeeper/TestReadOnlyZKClient.java M hbase-zookeeper/src/test/java/org/apache/hadoop/hbase/zookeeper/TestZKNodeTracker.java Wait until ZK is connected before progressing. On my slow zk, it could be a while post construction before zk connected. Using an unconnected zk caused test to fail. M hbase-zookeeper/src/test/java/org/apache/hadoop/hbase/zookeeper/TestZKMainServer.java Change session timeout to default 30s from 1s which was way too short. M hbase-zookeeper/src/test/resources/log4j.properties Set zk logs to DEBUG level in this module at least. Adds a ZooKeeperHelper class that has utility to help interacting w/ ZK.
Apache HBase [1] is an open-source, distributed, versioned, column-oriented store modeled after Google' Bigtable: A Distributed Storage System for Structured Data by Chang et al.[2] Just as Bigtable leverages the distributed data storage provided by the Google File System, HBase provides Bigtable-like capabilities on top of Apache Hadoop [3]. To get started using HBase, the full documentation for this release can be found under the doc/ directory that accompanies this README. Using a browser, open the docs/index.html to view the project home page (or browse to [1]). The hbase 'book' at http://hbase.apache.org/book.html has a 'quick start' section and is where you should being your exploration of the hbase project. The latest HBase can be downloaded from an Apache Mirror [4]. The source code can be found at [5] The HBase issue tracker is at [6] Apache HBase is made available under the Apache License, version 2.0 [7] The HBase mailing lists and archives are listed here [8]. The HBase distribution includes cryptographic software.
