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. ![]() 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.
