Cannot decode file block: Error decompressing block with deflate, possible data error

Hi,

While reading a file using avrocat tool, i am getting errors *Cannot decode
file block: Error decompressing block with deflate, possible data error.*

And when using avro-tools-1.7.6.jar i get Invalid Sync! errors.

Can anyone please tel me why these errors are coming, and is there a way to
correct the file now without loosing any data?

File was created using 1.7.4 C library

Thanks
Amit

I have also experienced deflate errors while reading some (very small % of files) with the C library (and written with the C# library).

Some sort of recovery tool would be a help for me as well.
It could just drop the broken block from the file.

Are all your files running into this, or just a few among the C-written ones? The file is possibly corrupt cause of missing bytes or other reasons (hard to tell specifically). Having more info on the behaviour or a sample such file to inspect may help.
