Subject hadoop 2.4 using Protobuf - How does downgrade back to 2.3 works ?
Date Fri, 17 Oct 2014 00:15:28 GMT
Hadoop 2.4.0 mentions that FSImage is stored using protobuf. So upgrade
from 2.3.0 to 2.4 would work since 2.4 can read old (2.3) binary format and
write the new 2.4 protobuf format.

After using 2.4, if there is a need to downgrade back to 2.3, how would
that work ?

Thanks,
