----------------------------------------
Summary: Failed Hive metastore start due to UnicodeDecodeError
Key: AMBARI-17245
URL: https://issues.apache.org/jira/browse/AMBARI-17245
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: trunk
Environment: CentOS6.5, LANG=ja_JP.UTF-8
Reporter: Masahiro Tanaka
Assignee: Masahiro Tanaka
When we start hivemestore in the environment described above, we got an error
{code}
Traceback (most recent call last):

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe3 in position 117: ordinal not in range(128)
{code}
I think the reason why this error occurs is because "/usr/lib/python2.6/site-packages/resource_management/libraries/functions/get_user_call_output.py". This script calls system command (e.g. {{cat}}), writes stdout & stderr in the tempfile, and read it. The outputs (stdout, stderr) are in UTF-8 encoded Japanese in the above environment.
When reading string from file, python regards the file as ASCII encoded by default. But if the file is utf-8 encoded, this causes an error.
We should decode UTF-8 when reading the file.
