Can you tell a bit more about this? well yes I loose data-locality - but HBase is not that well in maintaining that anyway - When starting up it does not distribute shards to the HDFS nodes that has data but pulls randomly. It gets locality either by "major compact" or waiting for compaction to re-write everything again. I may get equally good data locality with Ceph-based SSD as with local HDDs (which I currently have) Jesper _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
