Alex Araujo commented on HBASE-14791: ------------------------------------- Those build failures look unrelated. HBase-0.98-on-Hadoop-1.1 has been failing with a compilation error since #[1132|https://builds.apache.org/job/HBase-0.98-on-Hadoop-1.1/1132/]: {noformat} [ERROR] /home/jenkins/jenkins-slave/workspace/HBase-0.98-on-Hadoop-1.1/hbase-common/src/main/java/org/apache/hadoop/hbase/security/UserProvider.java:[70,49] error: cannot find symbol {noformat} HBase-0.98-matrix appears to have unrelated test failures. Most of the failures have been around since #[258|https://builds.apache.org/job/HBase-0.98-matrix/258/]. These are new, but unrelated: *jdk=latest1.7,label=Hadoop* java.lang.ExceptionInInitializerError: null at org.apache.hadoop.hbase.HBaseConfiguration.checkDefaultsVersion(HBaseConfiguration.java:73) hbase-default.xml file seems to be for and old version of HBase (0.98.16), this version is 0.98.17-SNAPSHOT java.lang.ExceptionInInitializerError: null at org.apache.hadoop.hbase.HBaseConfiguration.checkDefaultsVersion(HBaseConfiguration.java:73) at org.apache.hadoop.hbase.HBaseConfiguration.addHbaseResources(HBaseConfiguration.java:105) at org.apache.hadoop.hbase.HBaseConfiguration.create(HBaseConfiguration.java:120) at org.apache.hadoop.hbase.HBaseCommonTestingUtility.<init>(HBaseCommonTestingUtility.java:46) at org.apache.hadoop.hbase.TestClassFinder.<clinit>(TestClassFinder.java:57) Could not initialize class org.apache.hadoop.hbase.TestClassFinder java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.hbase.TestClassFinder Could not initialize class org.apache.hadoop.hbase.util.TestCoprocessorClassLoader java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.hbase.util.TestCoprocessorClassLoader Could not initialize class org.apache.hadoop.hbase.util.TestDynamicClassLoader java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.hbase.util.TestDynamicClassLoader *jdk=latest1.6,label=Hadoop* java.lang.NoSuchFieldError: in at org.apache.hadoop.hbase.codec.CellCodecWithTags$CellDecoder.parseCell(CellCodecWithTags.java:86) at org.apache.hadoop.hbase.codec.BaseDecoder.advance(BaseDecoder.java:67) at org.apache.hadoop.hbase.codec.TestCellCodecWithTags.testCellWithTag(TestCellCodecWithTags.java:76) java.lang.NoSuchFieldError: in at org.apache.hadoop.hbase.codec.KeyValueCodec$KeyValueDecoder.parseCell(KeyValueCodec.java:70) at org.apache.hadoop.hbase.codec.BaseDecoder.advance(BaseDecoder.java:67) at org.apache.hadoop.hbase.codec.TestKeyValueCodec.testOne(TestKeyValueCodec.java:80) > Batch Deletes in MapReduce jobs (0.98) > -------------------------------------- > > Key: HBASE-14791 > URL: https://issues.apache.org/jira/browse/HBASE-14791 > Project: HBase > Issue Type: Bug > Affects Versions: 0.98.16 > Reporter: Lars Hofhansl > Assignee: Alex Araujo > Labels: mapreduce > Fix For: 0.98.17 > > Attachments: HBASE-14791-0.98-v1.patch, HBASE-14791-0.98-v2.patch, > HBASE-14791-0.98.patch > > > We found that some of our copy table job run for many hours, even when there > isn't that much data to copy. > [~vik.karma] did his magic and found that the issue is with copying delete > markers (we use raw mode to also move deletes across). > Looking at the code in 0.98 it's immediately obvious that deletes (unlike > puts) are not batched and hence sent to the other side one by one, causing a > network RTT for each delete marker. > Looks like in trunk it's doing the right thing (using BufferedMutators for > all mutations in TableOutputFormat). So likely only a 0.98 (and 1.0, 1.1, > 1.2?) issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
