The goal here is I need to import data from MS SQL Server database to HDFS. The connectivity between Hadoop Cluster and MS SQL Server works fine. I confirmed this by TELNETing to port 1433. I am also able to --list-tables. [root@api1.dev ~]# sudo -u XXXXXXX /usr/hdp/current/sqoop-client/bin/sqoop list-tables --connect "jdbc:sqlserver://XX.XX.XXX.XXX:1433;database=XXXXXXXXXX;username=XXXXXXXX;password=XXXXXXXX"

I am running a simple sqoop import command which in turn runs a map reduce. I am testing this after standing up the cluster...I see this error from the logs : [2018-06-26 21:02:59,672] {bash_operator.py:76} INFO - main : requested yarn user is ods_archive

After checking the file system I see the directories do not have execute permissions :

Am I missing somewhere to set the permissions ?

Team, I build a new cluster and we have jobs to pull data out of MS SQL Server. MS SQL Server listens on port 1433 and our Network Security team has denied to open firewall between our Hadoop Cluster and MS SQL Server saying that port 1433 is a non secure port. MS SQL DBAs said that they cannot enable SSL on the DB side because other applications(legacy) would not be able to connect to MS SQL Server. Now from hadoop side we need to ensure our connections are secure. Has anybody faced this situation ? thanks Kumar

@Jay Kumar Sensharma Thanks for your reply. Looks like there were stale alerts. All the alerts went away after I restarted the ambari agents

The nodes in my cluster does not have direct access to Internet and so we were given proxies. I am referring to the document: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.0.0/bk_ambari-administration/content/ch_setting_up_an_internet_proxy_server_for_ambari.html I am trying to add no_proxies for few nodes, but as soon as add more than one node with pipe delimmitedf, ambari server does not restarts. Has anybody faced this situation ?

In my PROD environment, Infrastructure team is going to patch Top of the Rack switches and I came to know we do not have HA enabled( from switch side). My understanding is my cluster would not function with switch going down. Am I correct ? Also, what are the services I need to stop? Thanks Kumar
