Netstat show only 1 PID running from 8671

I tried to change the port but the error still appears. I change the port to 8671. . Failed to start ping port listener of: Could not open port 8671 because port already used by another process:

dcedielunesa · ‎05-11-2018

can I just use any port for ping port as long as it is not used by any application?

Hi have you solve this problem? I am also having same problem as yours.

dcedielunesa · ‎04-20-2018

dcedielunesa · ‎04-15-2018

thank you for your fast response @Geoffrey Shelton Okot. I already know that --map-column-hive is used to override the default mapping from SQL type to Hive type. Is there any other way to get rid of that error without using --map-column-hive??

dcedielunesa · ‎04-15-2018

I'm only encountering this error when I import from mssql windows server 2003. When I import from MYSQL 5.5 to MYSQL 5.6 it does not have any problem. I'm using sqljdbc4.jar for the sql driver. I also attached the screen shot of the error. Please help me getting rid this error without mapping timestamp column to string.

dcedielunesa · ‎03-27-2018

thank you for answering my questions sir, do you mean I have to alter the table in mysql when adding surrogate int PK?

dcedielunesa · ‎03-24-2018

dcedielunesa · ‎03-23-2018

Okey, Thanks a lot for explaining it to me very well. . I really have a lot of things needed to learn for this job.

dcedielunesa · ‎03-23-2018

The import will succeed if I will set the mappers to 1. I also notice that when I'm not using 1 mapper the yarn memory will be fully consumed

dcedielunesa · ‎03-23-2018

here's the stderr and stdout stdout.txt & stderr.txt

dcedielunesa · ‎03-23-2018

NO, I don't use split-by when I set mappers to 1 or in any

dcedielunesa · ‎03-23-2018

yes I am using --direct
