Why is hue so slow?

Hello.
Question about Cloudera-cdh 4
When using Hue to execute Hive queries, the execution time of the simplest query: reaches 5 (!) Hours. At the same time, the load on the cluster nodes is so high that the response in the ssh console takes more than a minute. Reading loadavg Node1 40 is the most powerful node. Cloudera Manager Node2 20 -- Node3 20 -- Node4 20 -- At the same time, if you run the same query in the Hive console: hive hive> select count(*) from table_name; The request only takes 30 minutes to complete. And loadavg on nodes does not exceed 10. Why is this happening and how to fix it? OS: CentOS 6.5 Coudera-cdh 4.4
select count(*) from table_name
