niuge01 opened a new pull request #3570: [HOTFIX] Fix FileNotFound error when concurrent loading URL: https://github.com/apache/carbondata/pull/3570 ### Why is this PR needed? When multiple threads use SDK write data, they will transfer CarbonLoadModel parameter with the same Configuration object, the following process may use an CarbonLoadModel which set by other thread, this will lead to a series of problems, such as: 2020-01-09 14:42:47 ERROR CarbonFactDataWriterImplV3:390 - Problem while writing the index file org.apache.carbondata.core.datastore.exception.CarbonDataWriterException: Problem while copying file from local store to carbon store at org.apache.carbondata.core.util.CarbonUtil.copyCarbonDataFileToCarbonStorePath(CarbonUtil.java:2772) at org.apache.carbondata.core.util.CarbonUtil.copyCarbonDataFileToCarbonStorePath(CarbonUtil.java:2721) at org.apache.carbondata.processing.store.writer.AbstractFactDataWriter.commitCurrentFile(AbstractFactDataWriter.java:277) at org.apache.carbondata.processing.store.writer.v3.CarbonFactDataWriterImplV3.closeWriter(CarbonFactDataWriterImplV3.java:387) at org.apache.carbondata.processing.store.CarbonFactDataHandlerColumnar.closeHandler(CarbonFactDataHandlerColumnar.java:508) at org.apache.carbondata.processing.loading.steps.CarbonRowDataWriterProcessorStepImpl.processingComplete(CarbonRowDataWriterProcessorStepImpl.java:233) at org.apache.carbondata.processing.loading.steps.CarbonRowDataWriterProcessorStepImpl.finish(CarbonRowDataWriterProcessorStepImpl.java:211) at org.apache.carbondata.processing.loading.steps.CarbonRowDataWriterProcessorStepImpl.doExecute(CarbonRowDataWriterProcessorStepImpl.java:175) at org.apache.carbondata.processing.loading.steps.CarbonRowDataWriterProcessorStepImpl.execute(CarbonRowDataWriterProcessorStepImpl.java:129) at org.apache.carbondata.processing.loading.DataLoadExecutor.execute(DataLoadExecutor.java:52) at org.apache.carbondata.hadoop.api.CarbonTableOutputFormat$1.run(CarbonTableOutputFormat.java:278) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.io.FileNotFoundException: D:\Workspace\Carbon-Master\integration\flink\target\test-classes\data\temp\8df45d4dc38449c69147083cdbe79e4d\part-0-156_batchno0-0-null-1578552167465.carbondata (系统找不到指定的路径。) at java.io.FileOutputStream.open0(Native Method) at java.io.FileOutputStream.open(FileOutputStream.java:270) at java.io.FileOutputStream.<init>(FileOutputStream.java:213) at java.io.FileOutputStream.<init>(FileOutputStream.java:101) at org.apache.carbondata.core.datastore.filesystem.LocalCarbonFile.getDataOutputStream(LocalCarbonFile.java:371) at org.apache.carbondata.core.datastore.filesystem.LocalCarbonFile.getDataOutputStream(LocalCarbonFile.java:365) at org.apache.carbondata.core.datastore.impl.FileFactory.getDataOutputStream(FileFactory.java:231) at org.apache.carbondata.core.util.CarbonUtil.copyLocalFileToCarbonStore(CarbonUtil.java:2799) at org.apache.carbondata.core.util.CarbonUtil.copyCarbonDataFileToCarbonStorePath(CarbonUtil.java:2756) ... 15 more ### What changes were proposed in this PR?
