All cluster hosts must use the same JDK update level.Īll JDK 8 updates, from the minimum required version, are supported in Cloudera Enterprise 6 unless specifically excluded. Running CDH nodes within the same cluster on different JDK releases is not supported. Cloudera excludes or removes support for select Java Unless specifically excluded, Cloudera supports later updates to a major JDK release from the release that support was introduced. Oracle JDK 9 is not supported in any Cloudera Manager or CDH version. You must recompile your applications using JDK 8 before upgrading to CDH 6. For installation and migration instructions, see Upgrading the JDK.Īpplications compiled with JDK 7 are not supported on CDH 6. OpenJDK 8 is supported in Cloudera Enterprise 6.1.0 and higher, as well as Cloudera Enterprise 5.16.1 and higher. JDK 8 is also supported in CDH 5.3 and higher. Supported in Cloudera Manager 6 and CDH 6. Manager 6.x must use JDK 8 on all cluster hosts. Although JDK 7 is supported on all versions of CDH 5, a CDH 5.x cluster that is managed by Cloudera Cloudera Manager 6 and CDH 6 do not support JDK 7. In general, for heap sizes above 32 GB, multiply the amount of heap you need by 1.5. If you need 32 GB or more, set your heap size to 48 GB or higher to account for the If you do not need more than 32 GB heap, set your heap size to 31GB or less to avoid this issue. This means that a heap size slightly less than 32 GB can hold more objects than a heap For larger heap sizes, 8-byte pointers are required. If installing the JDK by using a tar.gz bundle (for example) and the library/desktop/harfbuzz package is missing, a runtime link failure will occur when this package is needed.Note: A Java optimization called compressed oops (ordinary object pointers) enables a 64-bit JVM toĪddress heap sizes up to about 32 GB using 4-byte pointers. If this library is missing, then the pkg mechanism will require it during installation of the JDK. It should always be considered as required. This is a desktop library, but the font processing it does is part of some common backend server workloads. Used directly by libraries such as Pango, and the layout Unicode text to glyph indices and positions. Summary: HarfBuzz is an OpenType text shaping engineĭescription: HarfBuzz is a library for text shaping, which converts This package is provided for Solaris 11.3 and later. The OS provide the package library/desktop/harfbuzz as part of the Oracle JDK-11.0.10 and later for Solaris 11 requires that Consequently, there may be interoperability issues when is set to true and the client trusts more CAs than the server implementation limit.Ĭlient-libs/2d ➜ Oracle JDK11u for Solaris Now Requires harfbuzz to be Installed Also, some server implementations do not allow handshake messages to exceed 2^14 bytes. Note that if the client trusts more CAs than the size limit of the extension (less than 2^16 bytes), the extension is not enabled. The default value of the property is false. This extension is always present for client certificate selection, while it is optional for server certificate selection.Īpplications can enable this extension for server certificate selection by setting the system property to true. With this JDK release, the "certificate_authorities" extension is supported for TLS 1.3 in both the client and the server sides. It is used to indicate the certificate authorities (CAs) that an endpoint supports and should be used by the receiving endpoint to guide certificate selection. The "certificate_authorities" extension is an optional extension introduced in TLS 1.3. Security-libs/ ➜ Support for certificate_authorities Extension
