JIRAs

Full list of JIRAs fixed in version 0.1.0

Caveats

  1. Myriad has a compile dependency on Hadoop 2.7.0 and Mesos 0.24.1 versions. It was well tested against these versions. However, binary compatibility against other Hadoop/Mesos versions is not guaranteed.
  2. The /api/cluster/flexup and /api/cluster/flexdown REST end points support "constraints" parameter. However, the web UI does not yet support specifying this parameter.
  3. MYRIAD-153: Place holder tasks not getting cleaned up. A work around if this problem is hit is to restart the zero profile NM using flex down and flex up APIs.
