Hello all,
I’m getting an error when attempting to create a table and load data from a CSV file using “create a new table from a file” option in Hue. I’m on HDP 2 and have entered in the Groups and Users proxy settings into the webhcat-site.xml file as well.
The table gets created but it looks like when it is trying to load the data, that’s when it errors out. I get this error message.
HCatClient error executing hive query: {“error”:”User: hcat is not allowed to impersonate arench”} (error 500)
I’m assuming the config is missing from my webhcat-site.xml page but I’m not 100% on that. Here’s my webhcat-site.xml file contents nevertheless.
