> Key: HAWQ-1540
> URL: https://issues.apache.org/jira/browse/HAWQ-1540
> Project: Apache HAWQ
> Issue Type: Improvement
> Components: PXF
> Reporter: Alexander Denissov
> Assignee: Alexander Denissov
> Fix For: 2.3.0.0-incubating
>
>
> Currently PXF accepts --hadoop-home parameter for init command, which is used
> in greenplum-embedded deployment to specify where Hadoop client artifacts are
> installed. The desired behavior is:
> - do not accept any parameters during init command
> - rely on configuration provided by conf/pxf-env.sh file
> - introduce new HADOOP_DISTRO variable that can take the following values:
> [<empty>, HDP, CDH, CUSTOM]
> - when the value is empty -- the script will check for existence of
> RPM-installed HDP hadoop-client in /usr/hdp/current/hadoop-client/client and
> if found, will use HDP-specific private classpath template to generate new
> pxf-private.classpath file. If not found, the script will check for existence
> of RPM-installed CDH hadoop-client in /usr/lib/hadoop/client and if found,
> will use CDH-specific private classpath template to generate new
> pxf-private.classpath file. If none were found, the script will check for a
> TAR-installed hadoop client in the directory specified by the new variable
> HADOOP_ROOT under ${HADOOP_ROOT}/hadoop/share/hadoop/common/lib. If found,
> the script will use TAR-specific private classpath template to generate new
> pxf-private.classpath file. That template assumes Hadoop client (and
> optionally Hive and HBase clients) are installed under a common directorythat
> is pointed to by HADOOP_ROOT variable. A user will have to specify this
> variable or edit the pxf-env.sh config file before attempting pxf init
> command. If HADOOP_ROOT is not set of
> ${HADOOP_ROOT}/hadoop/share/hadoop/common/lib directory does not exist, the
> script will error out.
> - when the value is HDP -- the script will check for existence of
> RPM-installed HDP hadoop-client in /usr/hdp/current/hadoop-client/client and
> if found, will use HDP-specific private classpath template to generate new
> pxf-private.classpath file. If not found, the script will check for
> TAR-installed distribution as described above.
> - when the value is CDH -- the script will check for existence of
> RPM-installed CDH hadoop-client in /usr/lib/hadoop/client and if found, will
> use CDH-specific private classpath template to generate new
> pxf-private.classpath file. If not found, the script will check for
> TAR-installed distribution as described above.
> - when the value is CUSTOM -- the script will check for TAR-installed
> distribution as described above, except it will not error out if HADOOP_ROOT
> is not set or points to a non-existing directory. If HADOOP_ROOT is set, the
> value will be substituted in tar-based template, even if the directory does
> not yet exist. If HADOOP_ROOT is not set, the tar-based template is copied to
> the conf/pxf-private.classpath file and the user will have to perform the
> editing of this file.
