-
-Here are instructions for enabling X-Pack with Elasticsearch and Kibana: https://www.elastic.co/guide/en/x-pack/5.6/installing-xpack.html
-
-You need to be sure to add the appropriate username and password for Elasticsearch and Kibana to enable external connections from Metron components. e.g. the following will create a user "transport_client_user" with password "changeme" and "superuser" credentials.
-
-```
-sudo /usr/share/elasticsearch/bin/x-pack/users useradd transport_client_user -p changeme -r superuser
-```
-
-Once you've picked a password to connect to ES, you need to upload a 1-line file to HDFS with that password in it. Metron will use this file to securely read the password in order to connect to ES securely.
-
-Here is an example using "changeme" as the password
-
-```
-echo changeme > /tmp/xpack-password
-sudo -u hdfs hdfs dfs -mkdir /apps/metron/elasticsearch/
-sudo -u hdfs hdfs dfs -put /tmp/xpack-password /apps/metron/elasticsearch/
-sudo -u hdfs hdfs dfs -chown metron:metron /apps/metron/elasticsearch/xpack-password
-```
-
-New settings have been added to configure the Elasticsearch client. By default the client will run as the normal ES prebuilt transport client. If you enable X-Pack you should set the es.client.class as shown below.
-
-Add the es settings to global.json

-```
-/usr/metron/0.5.1/config/zookeeper/global.json ->

- "es.client.settings" : {

- "es.xpack.username" : "transport_client_user",
- "es.xpack.password.file" : "/apps/metron/elasticsearch/xpack-password"

-
-Submit the update to Zookeeper
-
-```
-$METRON_HOME/bin/zk_load_configs.sh -m PUSH -i METRON_HOME/config/zookeeper/ -z $ZOOKEEPER
-```
-
-The last step before restarting the topology is to create a custom X-Pack shaded and relocated jar. This is up to you because of licensing restrictions, but here is a sample Maven pom file that should help.

-Once you've built the elasticsearch-xpack-shaded-5.6.2.jar, it needs to be made available to Storm when you submit the topology. Create a contrib directory for indexing and put the jar file in this directory.
-
-```
-/usr/metron/0.5.1/indexing_contrib/elasticsearch-xpack-shaded-5.6.2.jar

-Now you can restart the Elasticsearch topology. Note, you should perform this step manually, as follows.

-```

+
+#### Solution
+
+This can occur when an HDFS Client is not installed on the Storm worker nodes. This might occur on any Storm worker node where an HDFS Client is not installed. Installing the HDFS Client on all Storm worker nodes should resolve the problem.
