Hi Team, We have multitenant platform , We are using hdp 2.4 with kerborose authentication. since its multi tenant/multi user platform we ahve different accounts setup per user. when different users run hive queries such as insert overwrite table XYZ select * from ABC; then hive by default refers to /tmp as scratchdir to do intermediate data processing .At the end when it tries to move data \ from /tmp to respective EZ for that user lets say /apps/hive/warehouse/<user-ez-dir> it fails with below error Failed with exception Unable to move source hdfs ://HDPXYZ/tmp/hive/<user_name>/<some encrypted string> to destination hdfs://HDPXYZ/apps/hive/warehouse/<user_ez_dir>. I know we can set scratchdir while running the script through -hiveconf. I am interested to know if we can sett somewhere per user basis as we can't set it globally in hive-site.xml as there are multiple users

Dear hortonworks team,I took an exam today morning .It was very frustrating experince with proctor .Last time I attempted hdpcd spark exam and I could experience that we should have good resolution monitor plugged in for better view.I did send emmail to certification@hortonworks team and they confirmed me saying yes yoou cab use extra monitor for better resolution.Today I was well set and it was 2:00 am in the night.exam started and suddenly proctor paused my exam saying you are using two computers..I did move the camera around the room there was nothing besides extra monitor.He didnt listen and asked me to close all the chrome session in between ...it didnt stop there , I was asked to shutdown my machine and when I relogin he finally asked me to remove the desktop monitor otherwise he said I cant launch the exam..It ate up all my time and couldnt focus on the task and had to remove my monitor..I could barely visualizae text on my lapton screen..even i was well prepared I couldnt attempt the passing questions even. For last 15 minutes suddenly exam got hang , I told to live monitor and followed his instructions to refresh the exam window ..nothing helped and after 10 minutes proctor said exam cannot be relaunched..you may contact hortonworks certification team for filing any petition if you receive failing grade..team request you to look into this..its very difficult when someone prepares for months and finally such things happen at exam time
