I am running Hadoop 3.2.1 and Hbase 2.2.3 on Centos8. I downloaded Hadoop from an Apache mirror following the Apache documentation precisely. Hadoop works just fine. I then downloaded HBase from an Apache mirror and followed the Apache documentation precisely.
When i try to run hbase version i receive this error:
/usr/hdeco/hadoop/bin/../libexec/hadoop-functions.sh: line 2366: HADOOP_ORG.APACHE.HADOOP.HBASE.UTIL.GETJAVAPROPERTY_USER: bad substitution
/usr/hdeco/hadoop/bin/../libexec/hadoop-functions.sh: line 2461: HADOOP_ORG.APACHE.HADOOP.HBASE.UTIL.GETJAVAPROPERTY_OPTS: bad substitution
HBase then goes on to print out the version information. if I run hbase-daemon.sh start master, i receive the same error, but HMaster does not show up in jps.
As per the Apache HBase documentation, because I am running a Hadoop version greater than 3.0.0, i have deleted all the jar files in the hbase/lib directory that contained the word hadoop. I received the same error both before and after deleting these jar files.
This is my first time posting anywhere. If I have not included enough, or the right, information, please let me know what you would like me to provide.

I installed Apache Kylin, following the official installation guide http://kylin.apache.org/docs/install/index.html, in HDP sandbox 2.6
When I run the script, $KYLIN_HOME/bin/kylin.sh start, I got the error below:
What can I do to fix this error?
Thanks in advance
Check if Hive service is up in your ambari, when Hive service is down Kylin cannot find it and gives the error. Check for .bash_profile as well. When those two issues are addressed kylin should be able to find location of hive dependency.
Kylin uses the find-hive-dependency.sh script to setup the CLASSPATH. This script uses a Hive CLI command (I test it with beeline) to query Hive env vars and extract the CLASSPATH from them.
beeline connect to Hive using the properties at kylin_hive_conf.xml but for some reason (probably due to the Hive version included in HDP 2.6) some of the loaded Hive properties cannot be set when the connection is stablished.
The Hive properties that causes the issue can be discarded for connecting to Hive to query the CLASSPATH, so, to fix this issue:
Edit $KYLIN_HOME/conf/kylin.properties and set kylin.source.hive.client=beeline
Open the find-hive-dependency.sh script, go to line 34 aprox and modify the line
hive_env=${beeline_shell} ${hive_conf_properties} ${beeline_params} --outputformat=dsv -e "set;" 2>&1 | grep 'env:CLASSPATH'
Just remove ${hive_conf_properties}
Check Hive depedencies have been configured by running the command find-hive-dependency.sh.
Now $KYLIN_HOME/bin/kylin.sh start should works.
I'm using Hadoop 0.23.8 pseudo distributed and HBase 0.94.8. My HBase master is failing with:
Server IPC version 5 cannot communicate with client version 4
I think this is because HBase is using hadoop-core-1.0.4.jar in its lib folder.
Now http://cloudfront.blogspot.in/2012/06/how-to-configure-habse-in-pseudo.html#.UYfPYkAW38s suggests I should replace this jar by copying:
the hadoop-core-*.jar from your HADOOP_HOME ...
but there are no hadoop-core-*.jars in 0.23.8.
Will this process work for 0.23.8, and if so, which jars should I be using?
TIA!
I gave up with this and am using hadoop 2.2.0 which works well (ish) with HBase.
I have Hadoop(pseudo distributed mode), Hive, sqoop and mysql installed in my local machine.
But when I am trying to run sqoop Its giving me the following error
Error: /usr/lib/hadoop does not exist!
Please set $HADOOP_COMMON_HOME to the root of your Hadoop installation.
Then I set the sqoop-env-template.sh file with all the information. Beneath is the snapshot of the sqoop-env-template.sh file.
Even after providing the hadoop hive path I face the same error.
I've installed
hadoop in /home/hduser/hadoop version 1.0.3
hive in /home/hduser/hive version 0.11.0
sqoop in /home/hduser/sqoop version 1.4.4
and mysql connector jar java-5.1.29
Could anybody please throw some light on what is going wrong
sqoop-env-template.sh is a template, meaning it doesn't by itself get sourced by the configurator. If you want it to have a custom conf and load it, make a copy as $SQOOP_HOME/conf/sqoop-env.sh.
Note: here is the relevant excerpt from bin/configure-sqoop for version 1.4.4:
SQOOP_CONF_DIR=${SQOOP_CONF_DIR:-${SQOOP_HOME}/conf}
if [ -f "${SQOOP_CONF_DIR}/sqoop-env.sh" ]; then
. "${SQOOP_CONF_DIR}/sqoop-env.sh"
fi
I have to connect pig to a hadoop which changed a little from Hadoop 0.20.0. I choose pig 0.7.0, and setting PIG_CLASSPATH by
export PIG_CLASSPATH=$HADOOP_HOME/conf
when I run pig, an error is reported like this:
ERROR org.apache.pig.Main - ERROR 2999: Unexpected internal error. Failed to create DataStorage
So, I copy hadoop-core.jar in $HADOOP_HOME to overwrite hadoop20.jar in $PIG_HOME/lib, then "ant". Now, I can run pig, but when I use dump or store, another error:
Pig Stack Trace

Does anyone have encountered this error, or is my compile way not right?
Thanks.
There is a section about this issue in the Pig FAQ which should give you a good idea what's wrong. Here is the outline taken from this page:
This usually happens when you are connecting hadoop cluster other than standard Apache hadoop 20.2 release. Pig bundles standard hadoop 20.2 jars in release. If you want to connect to other version of hadoop cluster, you need to replace bundled hadoop 20.2 jars with compatible jars. You can try:
do "ant"
copy hadoop jars from your hadoop installation to overwrite ivy/lib/Pig/hadoop-core-0.20.2.jar and ivy/lib/Pig/hadoop-test-0.20.2.jar
do "ant" again
cp pig.jar to overwrite pig-*-core.jar
Some other tricks is also possible. You can use "bin/pig -secretDebugCmd" to inspect the command line of Pig. Make sure you are using the right version of hadoop.
As pointed in this FAQ section, if nothing works I would advise just upgrading to a recent version of Pig after 0.9.1, Pig 0.7 is a bit old.
The Pig (core) jar has a bundled Hadoop dependency, which may differ from the version you want to use. If you have an old Pig version (< 0.9) the you have the option, to build a jar without Hadoop:
cd $PIG_HOME
ant jar-withouthadoop
cp $PIG_HOME/build/pig-x.x.x-dev-withouthadoop.jar $PIG_HOME
Then start Pig:
cd $PIG_HOME/bin
export PIG_CLASSPATH=$HADOOP_HOME/hadoop-core-x.x.x.jar:$HADOOP_HOME/lib/*:$HADOOP_HOME/conf:$PIG_HOME/pig-x.x.x-dev-withouthadoop.jar; ./pig
Newer Pig versions contain the prebuilt withouthadoop version (see this ticket) so you can skip the building process. Furthermore when you run pig it will pick up the withouthadoop jar from PIG_HOME rather than the bundled version, so you don't need to add withouthadoop.jar
to the PIG_CLASSPATH either (provided, that you run Pig from $PIG_HOME/bin)
..Back to your question:
Hadoop 0.20 and its modified variant (0.20-append?) can work even with the latest Pig distribution (0.11.1) :
You just need to do the followings:
unpack Pig 0.11.1
cd $PIG_HOME/bin
export PIG_CLASSPATH=$HADOOP_HOME/hadoop-core-x.x.jar:$HADOOP_HOME/lib/*:$HADOOP_HOME/conf; ./pig
If you still get "Failed to create DataStorage" it's worth to start Pig with -secretDebugCmd as Charles Menguy suggested, so that you
can see whether Pig gets the right Hadoop version..etc.
Did you remember to run start-all.sh from /usr/local/bin? I ran into the same problem and I basically retraced my steps in configuring Hadoop itself. I am able to use Pig now.
I'm working on a hadoop cluster with CDH4.2.0 installed and ran into this error. It's been fixed in later versions of hadoop but I don't have access to update the cluster. Is there a way to tell hadoop to use this jar when running my job through the command line arguments like
hadoop jar MyJob.jar -D hadoop.mapreduce.client=hadoop-mapreduce-client-core-2.0.0-cdh4.2.0.jar
where the new mapreduce-client-core.jar file is the patched jar from the ticket. Or must hadoop be completely recompiled with this new jar? I'm new to hadoop so I don't know all the command line options that are possible.
I'm not sure how that would work as when you're executing the hadoop command you're actually executing code in the client jar.
Can you not use MR1? The issue says this issue only occurs when you're using MR2, so unless you really need Yarn you're probably better using the MR1 library to run your map/reduce.
