read_state unimplemented! (RuntimeError) #72

Closed LenChang closed 9 years ago

LenChang commented 9 years ago

i got a RuntimeError and i couldn't solve it.

/usr/lib64/ruby/gems/1.8/gems/mongoriver-0.4.3/lib/mongoriver/abstract_persistent_tailer.rb:82:in `read_state': read_state unimplemented! (RuntimeError)

So...what's the problem with this Q___Q...

macobo commented 9 years ago

Would it be possible to give the whole log output of running mosql (including the command). There might be some info there about what is going wrong since I haven't seen this before.

LenChang commented 9 years ago

the command

mosql -c collections.yaml --mongo mongodb://xx.xxx.xxx.xx --sql postgres://xx.xxx.xxx.xx/name?password=1111 -vvv

the whole log

thanks for you help!!

macobo commented 9 years ago

Oh, it seems like you're using an old version of mosql that relied on mongoriver to also be an older version.

Update your mosql gem to be 0.4.0 and everything should start working.

Let me know if that doesn't help.

LenChang commented 9 years ago

when i updated mosql. The log print some ERROR messages

Yeah, not sure why rdoc is yelling at you, but everything seems OK.

Glad you got it working!
