Hi, I am planning to test the cephfs to replace hdfs. I am using Yarn (Hadoop 2.2.x) branch. I am wondering is there any jar available to test ceph with this version. Also how is the support of data locality in ceph. Thanks, Gurviner Singh ___ ceph-user

Hi ceph-users, We are using Ceph (radosgw) to store user generated images, as GET latency is critical for us, most recently I did some investigation over the GET path to understand where time spend. I first confirmed that the latency came from OSD (read op), so that we instrumented code to trac

[ceph-users] hashpspool and backfilling

Hi, Today I've noticed an interesting result of not have hashpspool enabled on a number of pools -- backfilling is delayed. Take for example the following case: a PG from each of 5 different pools (details below) are all mapped to the same three OSDs: 884, 1186, 122. This is of course bad for data
