It is recommended to update to this version.

If you are upgrading from a 1.5.x or 1.4.x line, please be sure to modify your /usr/local/nn-analytics/bin/nna_env file to override the NNA_MAIN export to point to org.apache.hadoop.hdfs.server.namenode.analytics.WebServerMain as opposed to com.paypal.namenode.WebServerMain as the com.paypal packages were removed as part of #175.

We have dropped support for Hadoop versions 2.4.x, 2.5.x, and 2.6.x. If you need updates from the NNA 1.6.x line back-ported to support one of these Hadoop versions please raise an issue or message @pjeli on the NNA Gitter. We will be dropping support for 2.x entirely as NNA moves closer to Apache adoption.

Please checkout the new /setCachedQuery, /getCachedQuery, and /removeCachedQuery APIs via the ReadTheDocs link below. This API is highly encouraged to use over querying API repeatedly.

Supported OS:
-CentOS/RedHat
