Starting the DataStax Enterprise process when DataStax Enterprise was installed from
the DataStax Installer with the No Services option or from a tarball.
If running a mixed-workload cluster (one or more datacenters for each type of node),
determine which nodes to start as analytics, Cassandra, and DSE Search nodes. Begin
with the seed nodes first — analytics seed node, followed by the Cassandra seed node
— then start the remaining nodes in the cluster one at a time. For more information,
see Multiple datacenter deployment.
Attention: Do not start all the nodes at the same time, because this causes
contention among nodes to become the Job Tracker.
Procedure
-
From the install directory:
Option |
Description |
Cassandra node |
$ bin/dse cassandra |
BYOH node |
$ bin/dse cassandra |
DSE Hadoop node |
$ bin/dse cassandra -t |
DSE Search node |
$ bin/dse cassandra -s |
Spark only node |
$ bin/dse cassandra -k ## Starts Spark trackers on a
cluster of analytics nodes |
Spark + DSE Hadoop |
$ bin/dse cassandra -k -t ## Starts a node in Spark and in
Hadoop mode |
SearchAnalytics node |
$ bin/dse cassandra -k -s ## Starts a node in SearchAnalytics
mode |
When multiple flags are used, list them separately on the command line. For
example, ensure there is a space between
-k
and
-s
in
dse cassandra -k -s
.
Attention: All nodes are
DataStax Enterprise nodes and run the Cassandra
database.
-
Start the DataStax agent:
$ ./datastax-agent/bin/datastax-agent
-
To check that your ring is up and running:
$ cd install_location
$ bin/nodetool status
