Subject CDH 5.5 - Kudu error not enough space remaining in buffer for op
Date Tue, 17 May 2016 20:45:21 GMT
What is the limit of columns in Kudu?

I am using 1000 gen dataset, specifically the chr22 table which has 500,000
rows x 1101 columns. This table has been built In Impala/HDFS. I am trying
to create a new Kudu table as select from that table. I get the following

Error while applying Kudu session.: Incomplete: not enough space remaining
in buffer for op (required 46.7K, 6.96M already used

When looking at http://pcsd-cdh2.local.com:8051/mem-trackers, I see the
following. What configuration needs to be tweaked?
