Error deploying Hive using the Ambari agent (MySQL JAVA Connector JAR file missing)

Apache Hive is a data warehouse software project built on top of Apache Hadoop for providing data summarization, query and analysis.Hive gives an SQL-like interface to query data stored in various databases and file systems that integrate with Hadoop.


I recently ran into an issue when deploying Hive using Ambari. Here’s what my personal Knowledge Base article on the issue.


When deploying Hive and Hive Metastore to a new node, the “Hive Metastore Start” task fails. At the bottom of stderr I found the following message:


File "/usr/lib/ambari-agent/lib/resource_management/core/", line 52, in __call__

    return self.get_content()

  File "/usr/lib/ambari-agent/lib/resource_management/core/", line 197, in get_content

    raise Fail("Failed to download file from {0} due to HTTP error: {1}".format(self.url, str(ex)))

resource_management.core.exceptions.Fail: Failed to download file from http://<my_node_host>:8080/resources/ mysql-connector-java.jar due to HTTP error: HTTP Error 404: Not Found


Root Cause

I did deploy the Amari, HDP and HDP Utils repositories on a local mirror host. It seems as if the Ambari Agent assumes that the MySQL JAVA Connector JAR file would also be hosted by my local mirror.

This could also happen if the repositories configured during deployment no longer host the MySQL JAVA Connector JAR file.


Once I figured the root cause out it was easy to solve the issue by using YUM to manually install the MySQL JAVA Connector JAR file:


#On the Linux/Unix host(s) experiencing the install error, issue the following command:

sudo yum -y -q install mysql-connector-java
