Subject | Upgrading from Apache Hadoop 18.3 to Cloudera 18.3 |
Date | Wed, 23 Sep 2009 11:24:11 GMT |
Hi All, I am in process of installing Cloudera's 18.3 on a test cluster that has Apache Hadoop 18.3 already running on it. I have some data that i would like to keep and not need to reformat HDFS. Are there any quirks that i should watch out for any other recommendations? Thanks, Usman | |
