Reflection always "in progress" 2.0.5

i have an issue with acceleration when I check the data set through the settings, it would say that the reflection is ‘In progress’. But when I click on the Job’s log and located the data set materializing job, it would say’completed’
No matter, the reflection would always say that ‘This reflection is not ready to accelerate queries’.

This issue was reported already here Reflection always says 'in progress'
but i find this problem after upgrading Dremio from 1.4.9 to 2.0.5. The O.S. is Centos6.

Can someone help me?

2.1.6 is currently the latest public release, maybe try upgrading to that version first?

i can’t upgrade to 2.1.6 because i need to use the 2.0.5
