[CARBONDATA-2548] When using presto to query a table on carbondata, the "Could not read blocklet details" exception is reported

• Type: Bug
• Status: Open
• Priority: Blocker

Description

I think it may be line 373 in CarbonTableInputFormat.java. When the CarbonInputSplit object was constructed, the detailInfo property was not initialized

 

                  while (((double) bytesRemaining) / splitSize > 1.1) {

                    int blkIndex = getBlockIndex(blkLocations, length - bytesRemaining);

                    splits.add(makeSplit(segment.getSegmentNo(), path, length - bytesRemaining,

                        splitSize, blkLocations[blkIndex].getHosts(),

                        blkLocations[blkIndex].getCachedHosts(), FileFormat.ROW_V1));

 

 

 

The detailed exception is as follows：
