Applies to:

Big Data Appliance Integrated Software - Version 4.12.0 to 4.12.0 [Release 4.10]
Linux x86-64

Symptoms

NOTE: In the examples that follow, user details, cluster names, hostnames, directory paths, filenames, etc. represent a fictitious sample (and are used to provide an illustrative example only). Any similarity to actual persons, or entities, living or dead, is purely coincidental and not intended in any manner. 

The final step of the BDA V4.12 install may show most cluster verification tests failing like below:

========================================================================================
TEST LOG STATUS TIME(s)
----------------------------------------------------------------------------------------
BDA_Cluster_Check bdacheckcluster.out    SUCCESS      139
Teragen-sort-validate_Test terasort.out    ERROR           22

ORAAH_Test oraah_test.out                    ERROR         182
----------------------------------------------------------------------------------------
Total time : 321 sec.
========================================================================================

 

Additionally the output logs show a problem with oracle user access to the HDFS /tmp directory  like below:

...
log4j:ERROR Either File or DatePattern options are not set for appender [DRFA].
Exception in thread "main" java.lang.RuntimeException: org.apache.hadoop.security.AccessControlException: Permission denied: user=oracle, access=EXECUTE, inode="/tmp":hdfs:supergroup:d-wx------
at org.apache.hadoop.hdfs.server.namenode.DefaultAuthorizationProvider.checkFsPermission(DefaultAuthoriza tionProvider.java:279)
at org.apache.hadoop.hdfs.server.namenode.DefaultAuthorizationProvider.check(DefaultAuthorizationProvider .java:260)
...

Caused by: org.apache.hadoop.security.AccessControlException: Permission denied: user=oracle, access=EXECUTE, inode="/tmp":hdfs:supergroup:d-wx------
...

 

Note: This will not impact BDA V4.12 upgrades because the HDFS /tmp is already created with the correct permissions and Mammoth upgrade should not change them.
