Frequently Asked Questions
Everything you need to know before choosing an Apache Kudu support partner.
24×7 Apache Kudu managed support across Kudu masters, tablet servers, WAL, block cache, and Impala query integration, plus tablet replica health checks, Apache Kudu performance tuning service, version upgrades, schema design review, and root cause analysis for every critical incident – delivered as part of our broader Big Data consulting services covering the full storage and query stack enterprises rely on.
An Apache Kudu tablet server crash is caused by WAL disk exhaustion, a kernel OOM kill when –block_cache_capacity_mb is oversized, or a hole punch failure on unsupported filesystems. Ksolves diagnoses via kudu-tserver.FATAL log clears WAL disk pressure or resizes block cache, and verifies filesystem support before restarting the tablet server.
Apache Kudu not working after startup is typically caused by NTP clock skew exceeding HybridClock tolerance, kudu-master failing Raft quorum with fewer than 2 of 3 masters reachable, or Impala losing connectivity due to kudu_client_connect_timeout expiry. Ksolves runs kudu cluster ksck, restores NTP synchronization, repairs master quorum, and validates end-to-end Impala query connectivity.
An Apache Kudu tablet under-replication error occurs when tablet servers go down leaving tablets with fewer replicas than the configured replication factor. Ksolves runs kudu cluster ksck to identify affected tablets, uses kudu remote_replica unsafe_change_config to restore Raft consensus on surviving replicas, and monitors recovery until ksck reports the cluster healthy.
Debugging Apache Kudu ingestion failures from Spark or NiFi PutKudu involves identifying schema mismatches between the ingestion client and the Kudu catalog table, write timeouts during tablet leader election, or stale tablet location metadata in the Kudu client cache. Ksolves validates schema consistency via the master web UI on port 8051, forces a client metadata refresh, and tunes write timeout parameters to stabilize ingestion throughput.
An Apache Kudu master server down event causes catalog metadata loss if fewer than 2 of 3 masters remain reachable for Raft quorum. Ksolves checks master status via the web UI on port 8051, restarts the kudu-master process, and verifies Raft leader election completes successfully via kudu master status before restoring client connectivity.
An Apache Kudu write timeout error occurs when a tablet has no elected Raft leader, when WAL and compaction compete for the same disk causing leader overload, or when NTP clock skew causes HybridClock to reject writes. Ksolves diagnoses via kudu-tserver /metrics write latency percentiles, separates WAL onto dedicated NVMe drives, and restores NTP synchronization to eliminate clock-related rejections.
Apache Kudu compaction issues occur when tablet servers accumulate MemRowSet flush debt faster than the maintenance manager can schedule compaction, typically when –fs_wal_dir and –fs_data_dirs share the same slow disk. Ksolves monitors compaction queue depth via the /maintenance-manager path on port 8050, separates WAL and data directories onto NVMe volumes, and tunes maintenance manager threads until lag clears.
An Apache Kudu leader election failure occurs when a tablet loses Raft quorum because more than half its replicas are unavailable, or when clock skew between tablet servers exceeds the Raft election timeout. Ksolves uses kudu cluster ksck to identify affected tablets, applies kudu remote_replica unsafe_change_config to force consensus on healthy replicas, and validates stable leader election across all tablets before closing the incident.
