Kevin Kong created CARBONDATA-2548:
--------------------------------------
Summary: When using presto to query a table on carbondata, the
"Could not read blocklet details" exception is reported
Key: CARBONDATA-2548
URL: https://issues.apache.org/jira/browse/CARBONDATA-2548
Project: CarbonData
Issue Type: Bug
Components: presto-integration
Affects Versions: 1.4.0
Reporter: Kevin Kong
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：
