Can any one please guide me in installing apache Nifi from cloudera manager (5.8). Do I have to install nifi stand with cloudera manager parcels, there are hardly any help i see on line. please help...
CDH does not include NiFi, so, if you did want to add it to a CDH cluster that leverages Cloudera Manager and parcels, it would need to be added via a custom parcel like the one @obar1 pointed out. If you prefer to build your own, the instructions are here:
Since the question was asked, the situation has changed. As soon as Hortonworks and Cloudera merged, NiFi became supported by Cloudera.
Shortly after the integrations with CDH were also completed, so that NiFi is now a fully supported and integrated component.
Please look into the documentation for the latest info at any time, but in general Cloudera Manager is now able to install NiFi.
