----------------------------------
Summary: Add another default case for finding *_HOME when not
explicitly defined
Key: SQOOP-1203
URL: https://issues.apache.org/jira/browse/SQOOP-1203
Project: Sqoop
Issue Type: Improvement
Components: tools
Affects Versions: 1.4.4
Reporter: Mark Grover
Assignee: Mark Grover
Currently, the {{configure-sqoop}} scripts that checks the value of various
_HOME variables (e.g. HADOOP_MAPRED_HOME, HCAT_HOME, etc.) has the following
heuristic:
1. Use the *_HOME variable's value, if defined.
2. If not, assign /usr/lib/<relevant location> to the variable.
3. If /usr/lib/<relevant location> doesn't exist, error out
I would like to propose to modify this to add one more case before we error out.
1. Use the *_HOME variable's value, if defined.
2. If not, assign /usr/lib/<relevant location> to the *_HOME variable.
3. If /usr/lib/<relevant location> doesn't exist, check for hadoop and hcat at
the same directory level as sqoop
4. If #3 fails as well, error out.
This is backwards compatible because it wouldn't be touching any of the
existing cases. It will just add more location to check for presence of hadoop,
hcat etc. before erroring out.
