+ The example above runs every test. You can trim the tests file to include
+ only the tests you wish to run.
+
+ In some clusters, the user under which MR jobs run is different from the user
+ under which Accumulo is installed, and this can cause failures running the
+ tests. Various configuration and permission changes can be made to help the
+ tests run, including the following:
+
+ * Opening up directory and file permissions on each cluster node so that the
MR
+ user has the same read/write privileges as the Accumulo user. Adding the MR
+ user to a shared group is one easy way to accomplish this. Access is
required
+ to the Accumulo installation, log, write-ahead log, and configuration
+ directories.
+ * Creating a user directory in HDFS, named after and owned by the MR user,
+ e.g., /user/mruser.
+ * Setting the ZOOKEEPER_HOME and HADOOP_CONF_DIR environment variables for the
+ MR user. These can be set using the mapred.child.env property in
+ mapred-site.xml, e.g.:
+
+ <property>
+ <name>mapred.child.env</name>
+
<value>ZOOKEEPER_HOME=/path/to/zookeeper,HADOOP_CONF_DIR=/path/to/hadoop/conf</value>
+ </property>
-
+ Each functional test is run by a mapper, and so you can check the mapper logs
+ to see any error messages tests produce.
