Merge "Make logging for sstable data corruption useful" from Raphael
...
"
When a corrupted sstable fails to be read either on regular read or in
regular compaction, our logging is not useful as it can't pinpoint
the SSTable that was being read from, also it may not print useful
details about the corruption.
For example, when a compaction fails on data corruption, a cryptic
message as follow will be dumped:
compaction_manager - compaction failed: std::runtime_error (compressed chunk failed checksum): retrying
there are two problems with the log above:
1) it doesn't tell us which sstable is corrupted
2) it doesn't tell us detailed info about the checksum failure on compressed chunk
with those problems fixed, we'll now get a much more useful message:
compaction_manager - compaction failed: sstables::malformed_sstable_exception (Failed to read partition
from SSTable /home/.../md-74-big-Data.db due to compressed chunk of size 3735 at file offset 406491
failed checksum, expected=0, actual=1422312584): retrying
tests: mode(dev).
