Migrating Atlas data
After Atlas is available on the Cloudera Private Cloud Base cluster, you must import the Atlas data that the Atlas migration exporter utility exported from the HDP 2.6.5.x cluster.
For a node with 4 cores and 8 GB of heap space, the estimated duration for import is 0.75 million entities per hour.
- Go to :
atlas.migration.mode.batch.size
: The recommended value is 300.-
atlas.migration.mode.workers
: The recommended value is 3 when using one Atlas Solr shard.The value to be set depends on the following calculation:
if ATLAS_SOLR_SHARDS > 1,atlas.patch.numWorkers=ATLAS_SOLR_SHARDS * 3
Additional patches are applied after the migration is completed. These are the properties that will help with improving the speed of patches.
