Installation and Configuration Issues
You can see generic installation issues here: MapR Installer Known Issues.
Upgrade Issues
- MD-4026
- Issue: After an upgrade to MapR 6.0.1 or later, Drillbits can fail to start if
the cluster has Drill 1.11 or Drill 1.12 and the Drill package is not upgraded as part
of the upgrade. This issue can also occur during a manual rolling upgrade. The issue
occurs because the upgrade process removes symlinks to MapR-FS jar files in the
/opt/mapr/lib
directory.
- 31038
- Issue: During an upgrade to MapR 6.0.1 from any other MapR release, the
following file is not updated
automatically:
/opt/mapr/hadoop/hadoop-2.7.0/etc/hadoop/log4j.properties
Without the properties updates, you cannot use the scheduler debug logger.
- 29752
- Issue: The Oozie process fails following a manual upgrade from MapR 5.2.x (MEP 3.0.1) to MapR 6.0 if Oozie is not upgraded to the MEP 4.0.0 version.
Indexing and Mapr Drill
- 28041
- Running multiple queries in sequence can cause drillbits to run out of direct memory.
Limiting records in large batches to 5KB may prevent this issue from occurring. Should
Drill return an out of memory exception, issue the following command to restart the
drillbits:
$ maprcli node services -name drill-bits -action restart -nodes <node host names separated by a space>

If you use the Google Guava library in your application and encounter the following error:
You must use version 18.0 of the library. If you use Maven, you can use the following dependency:Caused by: java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch;
<dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>18.0</version> </dependency>
MapR-DB
- 27057
- When you issue a maprcli table changelog add command, during the initial sync when the existing data is copied to the change log, the end-to-end latency during the initial 5 minutes can be high. After the initial sync, any latency will be small, specifically 2-4 seconds.
- MAPRDB-2092
- In the MapR Database, adding a table index or replicating a table fails if the cluster administrator (MAPR_USER) does not have write access to the parent volume of the table.
MapR-ES
- 31074
- MapR-ES APIs that make use of streams.rpc.timeout.ms are best effort APIs, the timeout is not guaranteed.
MapR Client
- 23624
- The same MapR client can access both secure and nonsecure clusters; however, a MapR
client that is configured to access a secure cluster can access a nonsecure cluster only
if these conditions are met:
- The secure cluster must be listed first in
mapr-clusters.conf
. - A user must obtain a ticket for the secure cluster even if the user wants to access only the nonsecure cluster.
- The secure cluster must be listed first in

- MON-3407
- Issue: If you are upgrading from a pre-6.0 version, the MapR Control System might
display 0 instances of webserver running in the Services page. This is

MapR Installer, Elasticsearch and Fluentd fail to start, and the Elasticsearch roles
file (
/opt/mapr/roles/elasticsearch

MapR PACC
Oozie
- 29634
- Issue: On a secure cluster, Oozie jobs can fail when the timeline server for the Hive-on-Tez user interface is configured with MapR-SASL.
- 29657

following error message appears exactly every 10 seconds:
This issue is caused by Jersey 1.9 minor bug.Class com.sun.jersey.server.wadl.generators.WadlGeneratorJAXBGrammarGenerator$8 can not access a member of class javax.ws.rs.core.Response with modifiers "protected" in at "resourcemenager.out log
