*Description* WSO2 Storage Server currently support only spinning up HDFS Name nodes at startup. After starting the WSO2 SS name node , the datanode should be spinnned off with using the 'hadoop' CLI tool provided in the SS installations 'bin' folder (ref: https://docs.wso2.com/display/SS110/Setting+up+Storage+Server+with+HDFS ). This is felt as a certain shortcoming in the SS HDFS provisioning process and should be addressed in SS future version 1.5.0. The solution is to implement the datanode as Carbon Component which loads at startup and spin of the itself based on a command line parameter given.
Benefits of this also include, Not necessary to install KDC for the datanode to operate on the OS. Easy to use and configure HDFS datanode The datanode can be started as a single SS pack On Wed, Aug 6, 2014 at 9:03 AM, Prabath Abeysekera <[email protected]> wrote: > Hi Poshitha, > > Would you be able to add a small description on why this is being > implemented and the design considerations, etc you might have had to come > up with while you;re into it? > > Cheers, > Prabath > > > On Tue, Aug 5, 2014 at 3:44 PM, Poshitha Dabare <[email protected]> wrote: > >> Hi, >> >> I was able to start the datanode comepenent is SS as OSGI bundle.
