From 99082698eb57801df06e98ae5a7f7dc6f8ed2c33 Mon Sep 17 00:00:00 2001 From: hui lai Date: Thu, 16 Apr 2026 11:31:51 +0800 Subject: [PATCH] [fix](insert) fix INSERT job statistics lost in show load after FE restart (#62331) ## Problem After a FE restart, `SHOW LOAD` for finished INSERT jobs shows all-zero `JobDetails` (`ScannedRows`, `LoadBytes`, etc.), even though the values were correct before the restart. ## Fix **`InsertLoadJob`** - Add `@SerializedName("jdj") private String jobDetailsJson` to capture a JSON snapshot of `loadStatistic` at the moment the job finishes. - In `setJobProperties()` (called when the job transitions to FINISHED/CANCELLED), snapshot `loadStatistic.toJson()` into `jobDetailsJson`. - Override `getJobDetailsJson()` to return the persisted snapshot when available, falling back to the live `loadStatistic` during execution. **`LoadJob`** - Extract `protected String getJobDetailsJson()` (defaults to `loadStatistic.toJson()`) so subclasses can override the stats source used by `getShowInfoUnderLock()`. **`OlapInsertExecutor`** - Remove the `!Config.enable_nereids_load` guard in `afterExec()` so that `recordFinishedLoadJob` is always called when `jobId != -1`. This ensures the job is persisted to the edit log and its statistics are captured regardless of the config value. ## Test Added `test_insert_statistic_after_fe_restart` docker regression test that: 1. Inserts rows via `INSERT INTO ... SELECT` 2. Reads and records `JobDetails` from `SHOW LOAD` 3. Restarts FE 4. Asserts `ScannedRows`, `LoadBytes`, `FileNumber`, `FileSize` are unchanged after restart --- .../doris/load/loadv2/InsertLoadJob.java | 19 ++++ .../org/apache/doris/load/loadv2/LoadJob.java | 6 +- ...t_insert_statistic_after_fe_restart.groovy | 92 +++++++++++++++++++ 3 files changed, 116 insertions(+), 1 deletion(-) create mode 100644 regression-test/suites/load_p0/insert/test_insert_statistic_after_fe_restart.groovy diff --git a/fe/fe-core/src/main/java/org/apache/doris/load/loadv2/InsertLoadJob.java b/fe/fe-core/src/main/java/org/apache/doris/load/loadv2/InsertLoadJob.java index fd456be4cabe07..6c204da1083033 100644 --- a/fe/fe-core/src/main/java/org/apache/doris/load/loadv2/InsertLoadJob.java +++ b/fe/fe-core/src/main/java/org/apache/doris/load/loadv2/InsertLoadJob.java @@ -48,6 +48,12 @@ public class InsertLoadJob extends LoadJob { @SerializedName("tid") private long tableId; + // Snapshot of loadStatistic.toJson() captured when the job finishes. + // loadStatistic is not persisted (no @SerializedName), so we save it here + // to survive FE restarts. + @SerializedName("jdj") + private String jobDetailsJson = null; + // only for log replay public InsertLoadJob() { super(EtlJobType.INSERT); @@ -91,6 +97,9 @@ public void setJobProperties(long transactionId, long tableId, long createTimest this.loadingStatus.setTrackingUrl(trackingUrl); this.loadingStatus.setFirstErrorMsg(firstErrorMsg); this.userInfo = userInfo; + // Snapshot the current loadStatistic so it survives FE restarts. + // loadStatistic itself is not annotated with @SerializedName and won't be persisted. + this.jobDetailsJson = this.loadStatistic.toJson(); } public AuthorizationInfo gatherAuthInfo() throws MetaNotFoundException { @@ -116,4 +125,14 @@ public Set getTableNames() throws MetaNotFoundException { throw e; } } + + @Override + protected String getJobDetailsJson() { + // Use the persisted snapshot when loadStatistic is empty (e.g. after FE restart). + // Fall back to the live loadStatistic during execution. + if (jobDetailsJson != null) { + return jobDetailsJson; + } + return loadStatistic.toJson(); + } } diff --git a/fe/fe-core/src/main/java/org/apache/doris/load/loadv2/LoadJob.java b/fe/fe-core/src/main/java/org/apache/doris/load/loadv2/LoadJob.java index 947ed64244d4a7..1ca2eb0556209b 100644 --- a/fe/fe-core/src/main/java/org/apache/doris/load/loadv2/LoadJob.java +++ b/fe/fe-core/src/main/java/org/apache/doris/load/loadv2/LoadJob.java @@ -790,7 +790,7 @@ protected List getShowInfoUnderLock() throws DdlException { jobInfo.add(TimeUtils.longToTimeString(finishTimestamp)); // tracking url jobInfo.add(loadingStatus.getTrackingUrl()); - jobInfo.add(loadStatistic.toJson()); + jobInfo.add(getJobDetailsJson()); // transaction id jobInfo.add(transactionId); // error tablets @@ -820,6 +820,10 @@ public String getResourceName() { return "N/A"; } + protected String getJobDetailsJson() { + return loadStatistic.toJson(); + } + protected long getEtlStartTimestamp() { return loadStartTimestamp; } diff --git a/regression-test/suites/load_p0/insert/test_insert_statistic_after_fe_restart.groovy b/regression-test/suites/load_p0/insert/test_insert_statistic_after_fe_restart.groovy new file mode 100644 index 00000000000000..cab13258e88a84 --- /dev/null +++ b/regression-test/suites/load_p0/insert/test_insert_statistic_after_fe_restart.groovy @@ -0,0 +1,92 @@ +// Licensed to the Apache Software Foundation (ASF) under one +// or more contributor license agreements.
