---------------------------------
Summary: Hcatalog's bin/hcat script doesn't respect HIVE_HOME
Key: HIVE-5046
URL: https://issues.apache.org/jira/browse/HIVE-5046
Project: Hive
Issue Type: Bug
Components: HCatalog
Affects Versions: 0.11.0
Reporter: Mark Grover
Assignee: Mark Grover
https://github.com/apache/hive/blob/trunk/hcatalog/bin/hcat#L81
The quoted snippet (see below) intends to set HIVE_HOME if it's not set (i.e.
HIVE_HOME is currently null).
{code}
if [ -n ${HIVE_HOME} ]; then
{code}
However, {{-n}} checks if the variable is _not_ null. So, the condition is
checking for the boolean inverse of what it's supposed to be checking for.
Moreover, {{-n}} checks requires the string being tested to be enclosed in
quotes.
