Hello guys, I'm importing a table to Hbase via Sqoop import, and i want to do some experimentations and measure the time written, based on some options in Hbase like Number of regions, Max. file size, pre-splitting, others... Can i rely on the number (315.1576 seconds) that i'm showing in this picture:
Thanks

You can view the job completion details if u launch <resourcemangerhost>:8080/cluster/apps/FINISHED
look for the respective Mapreduce associated to the sqoop job.

You can time your command and compare numbers if you do not trust the number reported by Sqoop MR Import job 🙂
time IMPORT_COMMAND (Linux)

Thanks for the suggestion @vrodionov.
So, there is no other way to measure the time that sqoop spends to import data to hbase?

What I suggested is to compare both times. If they close enough, than you can rely on both. If there is a significant discrepancy than I would go with Unix timing.

Shouldn't be <resourcemanagerhost>:8088/cluster/apps/FINISHED ?

sorry typo, 8088 is the port

yup, i figured out, but thanks @rkandula, i tested it and it worked. But now i have 3 types of different times:
214.51 seconds from shell
real 4m40.985s from Linux command
user 0m19.121s from Linux command
sys 0m5.181s from Linux command
2m50 seconds elapsed time from mapreduce job
What time should i consider about the real time of writing to hbase table?

i am not sure about unix command,what is the time duration u see in resourcemanager url

I see elapsed time 2m50 seconds and in the bottom : Aggregate Resource Allocation:53607 MB-seconds, 213 vcore-seconds
