Description

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

select `p`, `p1`, `p2`,`keyid` from hive_8b_rt where `_hoodie_commit_time`>'20210325141300'
