JanusGraph Hbase MapReduceIndexmanagement Configuration
|
Shubhram Mohanty <mohanty...@...>
Hi , Can someone share the exact configuration for JanusGraph MapReduceIndexmanagement with hbase as storage backend? I am currently facing an issue where the hbase rootdir is not getting picked and it is pointing to default value as "/hbase". I tried to use the following propertykeys : storage.hbase.ext.hbase.rootdir=/data/hbase janusgraphmr.ioformat.conf.storage.hbase.ext.hbase.rootdir=/data/hbase None of them is actually picked by MapReduceIndexmanagement class. Am I doing anything wrong here? Rest all of my configs are picked as I can see in the logs. Please revert on this thread if you have a solution for this? Regards, Shubhram |

Hi Shubhram, I'm trying something similar for reindex and deletion of index with Hbase as backend, were you able to resolve your issue? I'm getting the following error for my function call on
