Tim Armstrong commented on IMPALA-8408:
---------------------------------------
For future reference, I think the crux of the fix was deleting this code here:
https://gerrit.cloudera.org/#/c/10165/13/fe/src/main/java/org/apache/impala/catalog/HdfsPartition.java
{code}
// TODO: instead of raising an exception, we should consider marking this
partition
// invalid and moving on, so that table loading won't fail and user can
query other
// partitions.
for (FileDescriptor fileDescriptor: fileDescriptors_) {
StringBuilder errorMsg = new StringBuilder();
if
(!getInputFormatDescriptor().getFileFormat().isFileCompressionTypeSupported(
fileDescriptor.getFileName(), errorMsg)) {
throw new RuntimeException(errorMsg.toString());
}
}
{code}
