hadoop command in shell scripts give Kcov error

[bhaskarrana]

Hi Simon,

As hadoop command in shell script throwing error
$ kcov /tmp/out test.sh
O/P
kcov: error: ]} ${JAVA8_HOME_CANDIDATES[ is not an integer
kcov: error: ]}'
is not an integer
kcov: error: HADOOP_COMMON_DIR=./
is not an integer
kcov: error: HADOOP_COMMON_LIB_JARS_DIR=lib
is not an integer
kcov: error: HADOOP_COMMON_LIB_NATIVE_DIR=lib/native
is not an integer
kcov: error: HDFS_DIR=./
is not an integer

Following is the script
cat test.sh

#!/bin/bash
hadoop fs -ls

I really have no clue as to what causes this. Is the hadoop command a shell script as well?

Hi Simon, I will provide this with better example, as it has nothing to do with hadoop command.Probably will post it soon.

Hi Simon,

Here is sample

cat test
#!/usr/bin/env bash

BIGTOP_DEFAULTS_DIR=${BIGTOP_DEFAULTS_DIR-/etc/default}
[ -n "${BIGTOP_DEFAULTS_DIR}" -a -r ${BIGTOP_DEFAULTS_DIR}/bigtop-utils ] && . ${BIGTOP_DEFAULTS_DIR}/bigtop-utils

JAVA6_HOME_CANDIDATES=(
'/usr/lib/j2sdk1.6-sun'
'/usr/lib/jvm/java-6-sun'
'/usr/lib/jvm/java-1.6.0-sun-1.6.0'
'/usr/lib/jvm/j2sdk1.6-oracle'
'/usr/lib/jvm/j2sdk1.6-oracle/jre'
'/usr/java/jdk1.6'
'/usr/java/jre1.6'
)

This file gives error

cat testError.sh

. /home/abcaxis/A//abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/test

Output
kcov: error: 3BIGTOP_DEFAULTS_DIR=/etc/default

This file donot give error
cat testNoError.sh
. /home/abcaxis/A/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/test

The difference is the directory nested level
/home/abcaxis/A//abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/test
/home/abcaxis/A/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/abcdef/test
The no error script has one less levle than error one.

Yes, I'm afraid this is a bash PS4 limitation, which will cut the string after some character limit. Again, it might be good to test the --bash-method=DEBUG, although I don't think that will fix it either.
