Interesting! I will try the same versions of Hadoop and Hive, and will try and see if I can reproduce the issue faced by you

I am having the same problem and hadoop is definitely in the path as it logs the output of the version command(I am using version 0.20.2 download….and hive 0.6 download(not source from trunk).

Unable to determine Hadoop version information.
‘hadoop version’ returned:
classpath=/opt/hbase-install/hbase/hbase-0.20.6.jar:/opt/hbase-install/hbase/hba
se-0.20.6-test.jar:/deanconfig/hbase_config/:/opt/hbase-install/hbase/lib/zookee

Hi Jony,

I went through hive script.. and found this message in this code..

cli () {
CLASS=org.apache.hadoop.hive.cli.CliDriver
-
- # cli specific code
- if [ ! -f ${HIVE_LIB}/hive-cli-*.jar ]; then
- echo “Missing Hive CLI Jar”
- exit 3;
- fi
-
- if $cygwin; then
- HIVE_LIB=`cygpath -w “$HIVE_LIB”`
- fi
-
- version=$($HADOOP version | awk ‘{if (NR == 1) {print $2;}}’);
-
- # Save the regex to a var to workaround quoting incompatabilities
- # between Bash 3.1 and 3.2
- version_re=”^([[:digit:]]+)\.([[:digit:]]+)(\.([[:digit:]]+))?.*$”
-
- if [[ "$version" =~ $version_re ]]; then
- major_ver=${BASH_REMATCH[1]}
- minor_ver=${BASH_REMATCH[2]}
- patch_ver=${BASH_REMATCH[4]}
- else
- echo “Unable to determine Hadoop version information.”
- echo “‘hadoop version’ returned:”
- echo `$HADOOP version`
- exit 6
- fi
-
……………………….
+ execHiveCmd $CLASS “$@”
}

thus.. it is trying to determine Hadoop version by invoking Hadoop itself… can you please verify that you have Hadoop environment variable set and available to the script ?

When running ~/hive/bin/hive, I receive a message of:

“Unable to determine Hadoop version”
Hadoop version:

and then the cursor appears to be the same as root rather than hive>, and it does not execute any hive command at CLI. What did I do wrong in configuration or setting up hive environment. I did however got Hadoop working in all nodes including namenodes, secondary node, jobtracker, datanode and tasktracker.

Please help, I am frustrated.

Thanks,

hey Daves, sorry I was engaged with other stuffs! I am sure you must have figured your way out by now.. but still answering the question… yes, it means the same (however, I havent tried that..) I prefer keeping the Hadoop path as a variable and using it along (as in the article)..

“1. you must have hadoop in your path”

the “your path” refer to the environment path
# echo $PATH ?
