Installing and uninstalling Big Match Ambari service for Hortonworks or IBM Open Platform (V11.5.0.4)

Big Match Console

This component is installed on exactly one node. The default lifecycles are responsible for the following actions.

START

Starts the Big Match WebSphere® Liberty Profile instance and HBase REST service (if not already started).

STOP

Stops the Big Match WebSphere Liberty Profile instance.

INSTALL

• Checks prerequisites (ensures that WebSphere Liberty Profile ports are not already used).
• Installs the Big Match Red Hat Package Manager (if not already installed).
• Installs and configures a WebSphere Liberty Profile instance.
• Creates the Derby database.
• Creates directories on HDFS for use by various Big Match processes.
• Alters the configuration files for services that Big Match depends on, including HDFS, HBASE, ZOOKEEPER, YARN, MAPREDUCE2, OOZIE, and KNOX.
• Adds the Big Match Oozie workflows and sample property files to HDFS.
• Adds libraries to the Oozie server WAR file.

CONFIGURE

Does nothing.

STATUS

Returns the status of the WebSphere Liberty Profile instance.

RESTART

Runs STOP followed by START.

This component has two custom commands:

ADD_SAMPLE_DATA

Creates the bmSample1 table in HBase. Adds the sample data load file and a Big Match sample configuration for this table to HDFS. The table is then pme_enabled and loaded with 10,000 sample records.

REMOVE_SAMPLE_DATA

Removes the Big Match sample data load file from HDFS and removes the bmSample1 table from HBase.

Big Match Runtimes

This component is installed on one or more nodes and the default lifecycles are responsible for the following actions.

INSTALL

• Installs the Big Match Red Hat Package Manager (if not already installed).
• Creates the Big Match user and group 'bigmatch' if they do not exist.
• Creates the bigmatch-env.sh file.
• Configures the node based on what components are installed. If service HBASE has components (HBASE_CLIENT, HBASE_MASTER, HBASE_REGIONSERVER) installed on the node, then the Big Match HBase table extensions are added to the HBASE_CLIENT components lib directory. Additionally the HBase shell ruby script is extended with the pme library and its custom commands. If the node has the HBASE_REGIONSERVER component installed, the Big Match queue directory is created. If service HDFS has components (HDFS_CLIENT, DATANODE) installed on the node, then the Big Match Hadoop extensions are added to the HDFS_CLIENT components lib directory.

CONFIGURE

Writes the pme-site configuration to file /etc/conf/hadoop/pme-site.xml. Writes the bigmatch-config configuration to file /usr/ibmpacks/current/bigmatch/conf/consoleui/bm-config.xml.
