        LAst night we had a successful run of random walk. I looked in the logs from this run and did not see the metadata tablets being bounced around like the master had too much mountain dew. When we saw this behavior before there were also other issues that have since been fixed. Not sure if those issues caused this in some way. We will keep looking for this issue as we test.
