I had at one point Myriad working fine in MapR 5.0. I updated to 5.1, and repackaged my hadoop tgz for remote distribution and now I have two problems occurring.
1. At first when I had the mapr direct shuffle enabled per the yarn-site.xml on the myriad documentaion, node managers would not start, and would fail with the error below. 2. Once I removed the mapr shuffle from the yarn-site, I got node managers started however, when I tried to launch a size 0, I got the other error below. Not sure what's happening here. Any thoughts would be appreciated. Like I said, this was working with 5.0, and now doesn't work in 5.1. Thanks!
