Please find my responses below in bold -</P><P>the machine names from the error log are the expected ones? So this basically means: env-2 is <A href="http://example1.com">example1.com</A> and <A href="http://example2.com">example2.com</A> is your hdfs master node (port 8020 should be hdfs file service from the name node)? </P><P>------ <STRONG>Yes, env-2 is <A href="http://example1.com">example1.com</A> and <A href="http://example2.com">example2.com</A> is hdfs master node</STRONG></P><UL><LI>Are all the issues related to the communication between env-2 and your name node, or do you have other hosts involved as well? ------<STRONG>-- Yes, Other hosts are involved as well . Issue is seen other nodes as well.</STRONG></LI><LI>does the process on env-1 start 5 times a day, or is it started once and continues to run (sleeping instead of terminating)?<BR /><STRONG>--------- In env -1 , process runs once and continues to run . Only 5 files are moved to HDFS in a single day . We don't restart any process.</STRONG></LI><LI>the ticket renewal on env-1 is identical to the ticket renewal on env-2?<STRONG> ------ ticket renewal is identical in both the env.</STRONG></LI></UL><P>I am just wondering if it is possible, that your process on env-2 only takes the ticket at start-up, and when the ticket expires, it just doesn't pick the renewed ticket? If after a restart of your processes on env-2 all authentication issues are gone for the next around 20h, this might be the case. And if on env-1 the process is starting 5 times a day instead of continuously running it might be the reason that the issue is not occure on env-1. </P><P><STRONG>------ In env-1 , the process is continuously running and we don't restart the process.</STRONG></P><P><STRONG>------- In env-2 , when the GSS issue pops up, we restart our process and all authentication issues are gone for the next around 20 h.</STRONG></P><P><STRONG>My issue here is, why restart is needed for env-2 . As, in env-1 , all works good without any restart . <BR /></STRONG></P><P><STRONG>As I have mentioned in my previous comment, the only difference between env-1 and env-2 is the load and amount of files are moved to HDFS simultaneously is huge in env-2. <BR /></STRONG></P><P><STRONG><BR /></STRONG></P><P>Please comment, if you need any more information for analysis.<STRONG><BR /></STRONG></P><P><STRONG>Thank you<BR /></STRONG></P><P><STRONG><BR /></STRONG></P> Tue, 26 Dec 2017 20:01:38 GMT vishakhaa9 2017-12-26T20:01:38Z
