scan of small table stopped working (hangs)
Hi,
I have a small Accumulo test instance, that I installed following this page:
https://www.digitalocean.com/community/tutorials/how-to-install-the-big-data-friendly-apache-accumulo-nosql-database-on-ubuntu-14-04
I've been doing testing and was able to successfully run the SimpleIngestClient from the minicluster project and create a table, testTable.
After that, I could use the Accumulo shell and scan the table, after logging in as a user, "demo" and running "scan -t testTable".
However, tonight, after I brought up the machine and started Hadoop (/apps/hadoop/sbin/start-dfs.sh), then zookeeper (/apps/zookeeper/bin/zkServer.sh start) and finally, Accumulo (/apps/accumulo/bin/start-all.sh).
And then I started the Accumulo shell and logged in as "demo" and did "scan -t testTable" and it just hangs, with no output.
I found another thread that suggested enabling "debug on" and here is the output:
