Description
By the core trace generated by the OBT there is a SEGFAULT (null pointer deference):
Using host libthread_db library "/lib64/libthread_db.so.1". Core was generated by `dfuserver'. Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00007f4891216c00 in FileSprayer::getAPICopyClient (this=0x7f485bffdca0) at /home/centos/build/CE/platform/HPCC-Platform/dali/ft/filecopy.cpp:1526 1526 distributedSource->getClusterName(0, sourceClusterName);
The related source from filecopy.cpp:1519-1533
IAPICopyClient * FileSprayer::getAPICopyClient()
{
bool needCalcCRC = calcCRC();
if (needCalcCRC && !sources.item(0).hasCRC)
return nullptr;
StringBuffer sourceClusterName;
distributedSource->getClusterName(0, sourceClusterName);
Owned<IStoragePlane> sourcePlane = getDataStoragePlane(sourceClusterName.str(), false);
Owned<IStorageApiInfo> sourceAPIInfo = sourcePlane->getStorageApiInfo();
if (!sourceAPIInfo)
return nullptr;
The problem is in Spray operation when source file is not a distributed file and the distributedSource is nullptr.
A possible fix is:
IAPICopyClient * FileSprayer::getAPICopyClient()
{
bool needCalcCRC = calcCRC();
if (needCalcCRC && !sources.item(0).hasCRC)
return nullptr;
if (!distributedSource)
return nullptr;
StringBuffer sourceClusterName;
distributedSource->getClusterName(0, sourceClusterName);
Owned<IStoragePlane> sourcePlane = getDataStoragePlane(sourceClusterName.str(), false);
Owned<IStorageApiInfo> sourceAPIInfo = sourcePlane->getStorageApiInfo();
if (!sourceAPIInfo)
return nullptr; StringBuffer targetClusterName;
if (!distributedTarget)
return nullptr;
