tao meng created HUDI-1718:
------------------------------
Summary: when query incr view of mor table which has Multi level
partitions, the query failed
Key: HUDI-1718
URL: https://issues.apache.org/jira/browse/HUDI-1718
Project: Apache Hudi
Issue Type: Bug
Components: Hive Integration
Affects Versions: 0.7.0, 0.8.0
Reporter: tao meng
Fix For: 0.9.0
HoodieCombineHiveInputFormat use "," to join mutil partitions, however hive use
"/" to join muit1 partitions. there exists some gap, so modify
HoodieCombineHiveInputFormat's logical
test env
spark2.4.5, hadoop 3.1.1, hive 3.1.1
step1:
val df = spark.range(0, 10000).toDF("keyid")
.withColumn("col3", expr("keyid + 10000000"))
.withColumn("p", lit(0))
.withColumn("p1", lit(0))
.withColumn("p2", lit(6))
.withColumn("a1", lit(Array[String]("sb1", "rz")))
.withColumn("a2", lit(Array[String]("sb1", "rz")))
// bulk_insert df, partition by p,p1,p2
merge(df, 4, "default", "hive_8b",
DataSourceWriteOptions.MOR_TABLE_TYPE_OPT_VAL, op = "bulk_insert")
step2:
val df = spark.range(0, 10000).toDF("keyid")
.withColumn("col3", expr("keyid + 10000000"))
.withColumn("p", lit(0))
.withColumn("p1", lit(0))
.withColumn("p2", lit(7))
.withColumn("a1", lit(Array[String]("sb1", "rz")))
.withColumn("a2", lit(Array[String]("sb1", "rz")))
// upsert table hive8b
merge(df, 4, "default", "hive_8b",
DataSourceWriteOptions.MOR_TABLE_TYPE_OPT_VAL, op = "upsert")
step3:
start hive beeline:
set hive.input.format=org.apache.hudi.hadoop.hive.HoodieCombineHiveInputFormat;
set hoodie.hive_8b.consume.mode=INCREMENTAL;
set hoodie.hive_8b.consume.max.commits=3;
set hoodie.hive_8b.consume.start.timestamp=20210325141300; // this timestamp
is smaller the earlist commit, so we can query whole commits
