If you upgraded from 10.2 and you changed the distribution version, you need to verify the distribution version in the General properties of the cluster configuration.

Effective in version 10.2.1, Informatica assigns a default version to each Hadoop distribution type. If you configure the cluster configuration to use the default version, the upgrade process upgrades to the assigned default version if the version changes. If you have not upgraded your Hadoop distribution to Informatica's default version, you need to update the distribution version property.

For example, suppose the assigned default Hadoop distribution version for 10.2.1 is

n

, and for 10.2.2 is

n+1

. If the cluster configuration uses the default supported Hadoop version of

n

, the upgraded cluster configuration uses the default version of

n+1

. If you have not upgraded the distribution in the Hadoop environment you need to change the cluster configuration to use version

n

.

If you configure the cluster configuration to use a distribution version that is not the default version, you need to update the distribution version property in the following circumstances:

Informatica dropped support for the distribution version.
You changed the distribution version.
