**_Tips before filing an issue_** - Have you gone through our [FAQs](https://hudi.apache.org/learn/faq/)? - Join the mailing list to engage in conversations and get faster support at [email protected]. - If you have triaged this as a bug, then file an [issue](https://issues.apache.org/jira/projects/HUDI/issues) directly. **Describe the problem you faced** We have been using hudi 0.12.0 version and observed that our GCS listing and usage metrics have went high. When we brought this up in slack community, they have suggested to update to 0.13.1, we have updated our apps to 0.13.1 version and able to query the tables using hudi catalog from Trino. But when I tried setting the below property to leverage metadata to improve the query performance, we are unable to run the queries and seeing the errors. **hudi.metadata_enabled=true;** **To Reproduce** Steps to reproduce the behavior: 1. Enable metadata table in hudi 0.13.1 2. Set hudi.metadata_enabled=true in hudi catalog on Trino. 3. Now run any simple query to read data from hudi table. 4. We will see the error. **Expected behavior** A clear and concise description of what you expected to happen. Trino leverage the metadata and run the queries faster. **Environment Description** * Hudi version : 0.13.1 * Spark version : 3.2.2 * Hive version : 2.3.5 * Hadoop version : 3.2 * Storage (HDFS/S3/GCS..) : GCS * Trino Version : 402 (hudi-trino-bundle-0.12.1.jar placed in hudi plugin) * Running on Docker? (yes/no) : yes **Additional context** Add any other context about the problem here. **Stacktrace** ``` io.trino.spi.TrinoException: Failed to generate splits for at io.trino.plugin.hudi.HudiSplitSource.lambda$new$1(HudiSplitSource.java:98) at io.trino.plugin.hudi.split.HudiBackgroundSplitLoader$1.onFailure(HudiBackgroundSplitLoader.java:111) at com.google.common.util.concurrent.Futures$CallbackListener.run(Futures.java:1124) at com.google.common.util.concurrent.DirectExecutor.execute(DirectExecutor.java:31) at com.google.common.util.concurrent.AbstractFuture.executeListener(AbstractFuture.java:1270) at com.google.common.util.concurrent.AbstractFuture.complete(AbstractFuture.java:1038) at com.google.common.util.concurrent.AbstractFuture.setException(AbstractFuture.java:808) at com.google.common.util.concurrent.TrustedListenableFutureTask$TrustedFutureInterruptibleTask.afterRanInterruptiblyFailure(TrustedListenableFutureTask.java:141) at com.google.common.util.concurrent.InterruptibleTask.run(InterruptibleTask.java:88) at com.google.common.util.concurrent.TrustedListenableFutureTask.run(TrustedListenableFutureTask.java:82) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:833) Caused by: java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/util/Bytes at org.apache.hudi.common.bootstrap.index.HFileBootstrapIndex.<clinit>(HFileBootstrapIndex.java:94) at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Class.java:375) at org.apache.hudi.common.util.ReflectionUtils.getClass(ReflectionUtils.java:54) at org.apache.hudi.common.util.ReflectionUtils.loadClass(ReflectionUtils.java:89) at org.apache.hudi.common.bootstrap.index.BootstrapIndex.getBootstrapIndex(BootstrapIndex.java:163) at org.apache.hudi.common.table.view.AbstractTableFileSystemView.init(AbstractTableFileSystemView.java:109) at org.apache.hudi.common.table.view.HoodieTableFileSystemView.init(HoodieTableFileSystemView.java:108) at org.apache.hudi.common.table.view.HoodieTableFileSystemView.<init>(HoodieTableFileSystemView.java:102) at org.apache.hudi.common.table.view.HoodieTableFileSystemView.<init>(HoodieTableFileSystemView.java:93) at org.apache.hudi.metadata.HoodieTableMetadataUtil.getFileSystemView(HoodieTableMetadataUtil.java:1030) at org.apache.hudi.metadata.HoodieTableMetadataUtil.getPartitionFileSlices(HoodieTableMetadataUtil.java:1048) at org.apache.hudi.metadata.HoodieTableMetadataUtil.getPartitionLatestMergedFileSlices(HoodieTableMetadataUtil.java:996) at org.apache.hudi.metadata.HoodieBackedTableMetadata.getPartitionFileSliceToKeysMapping(HoodieBackedTableMetadata.java:378) at org.apache.hudi.metadata.HoodieBackedTableMetadata.getRecordsByKeys(HoodieBackedTableMetadata.java:207) at org.apache.hudi.metadata.HoodieBackedTableMetadata.getRecordByKey(HoodieBackedTableMetadata.java:142) at org.apache.hudi.metadata.BaseTableMetadata.fetchAllFilesInPartition(BaseTableMetadata.java:323) at org.apache.hudi.metadata.BaseTableMetadata.getAllFilesInPartition(BaseTableMetadata.java:141) at org.apache.hudi.metadata.HoodieMetadataFileSystemView.listPartition(HoodieMetadataFileSystemView.java:65) at org.apache.hudi.common.table.view.AbstractTableFileSystemView.lambda$ensurePartitionLoadedCorrectly$9(AbstractTableFileSystemView.java:306) at java.base/java.util.concurrent.ConcurrentHashMap.computeIfAbsent(ConcurrentHashMap.java:1708) at org.apache.hudi.common.table.view.AbstractTableFileSystemView.ensurePartitionLoadedCorrectly(AbstractTableFileSystemView.java:297) at org.apache.hudi.common.table.view.AbstractTableFileSystemView.getLatestBaseFiles(AbstractTableFileSystemView.java:497) at io.trino.plugin.hudi.query.HudiReadOptimizedDirectoryLister.listStatus(HudiReadOptimizedDirectoryLister.java:104) at io.trino.plugin.hudi.split.HudiBackgroundSplitLoader.loadSplits(HudiBackgroundSplitLoader.java:94) at io.trino.plugin.hudi.split.HudiBackgroundSplitLoader.lambda$start$0(HudiBackgroundSplitLoader.java:74) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:539) at com.google.common.util.concurrent.TrustedListenableFutureTask$TrustedFutureInterruptibleTask.runInterruptibly(TrustedListenableFutureTask.java:131) at com.google.common.util.concurrent.InterruptibleTask.run(InterruptibleTask.java:74) ... 4 more Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.util.Bytes at java.base/java.net.URLClassLoader.findClass(URLClassLoader.java:445) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:587) at io.trino.server.PluginClassLoader.loadClass(PluginClassLoader.java:126) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:520) ... 33 more ``` -- This is an automated message from the Apache Git Service.
