Will McQueen commented on FLUME-1303:
-------------------------------------
Fixed by replacing:
^java\.library\.path=([^\n])
...with:
^java\.library\.path=(.*)$
Tested with test script:
#!/bin/bash
TEST_STR=$(echo -e "prevline\\njava.library.path=nxnyn\\nnextline")
echo "original:|$TEST_STR|"
IFS=$'\n'
for line in $TEST_STR; do
echo "candidate:|$line|"
if [[ $line =~ ^java\.library\.path=(.*)$ ]]; then
echo FOUND
TEST_OUTPUT=${BASH_REMATCH[1]}
break
fi
done
unset IFS
echo "Result is: |$TEST_OUTPUT|"
Output of test script is as follows (and is correct):
original:|prevline
java.library.path=nxnyn
nextline|
candidate:|prevline|
candidate:|java.library.path=nxnyn|
FOUND
Result is: |nxnyn|
Also tested by running flume-ng with hadoop and hbase libs installed and with
hbase-env.sh containing the following uncommented line:
export HBASE_OPTS="$HBASE_OPTS -verbose:class -XX:+PrintGCDetails
-XX:+PrintGCDateStamps"
The output for java.library.path was as expected:
-Djava.library.path=:/usr/lib/hadoop/lib/native:/usr/lib/hadoop/lib/native:/usr/lib/hbase/bin/../lib/native/Linux-amd64-64
> java.library.path value is being truncated at first 'n' char

> Key: FLUME-1303
> URL: https://issues.apache.org/jira/browse/FLUME-1303
> Project: Flume
> Issue Type: Bug
> Components: Shell
> Affects Versions: v1.2.0
> Environment: RHEL 6.2 64-bit
> Reporter: Will McQueen
> Assignee: Will McQueen
> Priority: Blocker
> Fix For: v1.2.0
>
>
> In the flume-ng script, the '\' and 'n' characters are each being treated as
> delimiters instead of being treated as a newline character. This relates to
> the following line of code that is found in 2 places within the script:
> if [[ $line =~ ^java\.library\.path=([^\n]*) ]]; then
> This causes the java.library.path's value to be truncated at the first '\'
> or \n' character in its value.
> For example:
> [will@will-laptop flume-1.2.0-incubating-SNAPSHOT]$ bin/flume-ng agent -d
> ...results in a java.library.path of:
> -Djava.library.path=:/usr/lib/hadoop/lib/:/
> ..but should be:
>
> -Djava.library.path=:/usr/lib/hadoop/lib/native:/usr/lib/hadoop/lib/native:/usr/lib/hbase/bin/../lib/native/Linux-amd64-64
