kandi X-RAY | LZF Summary

LZF is a C# library typically used in Utilities, Compression, Deep Learning applications. LZF has no bugs, it has no vulnerabilities and it has low support. However LZF has a Non-SPDX License. You can download it from GitHub.

A simple C# LZF compression implementation which attempts to minimize memory allocations. While LZF compression might not have the great compression ratio of some algorithms, it is simple and extremely fast. This makes it great for real-time applications where you want some compression but need to prioritize speed and responsiveness, such as in game development. Some implementations of LZF unfortunately are a bit careless with memory allocations which could potentially cause some issues if you're on a platforms with limited memory and/or where you're trying to manage and minimize garbage collection. This implementation attempts to address this by allowing the re-use of a single buffer for all work and output. For more algorithm details, refer to Marc Lehmann's original release.

Acording to this answer: https://stackoverflow.com/a/51236918/16651073 tomcat falls back to default logging if it can resolve the location

Can you try to save the properties without the spaces.

The basic problem is that there are no backslashes in your string. Your source code has backslashes, but they are all escape signals. If you want to retain the backslashes in "WYSIWYG" style, use raw string mode:

QUESTION

Running into 'java.lang.OutOfMemoryError: Java heap space' when using toPandas() and databricks connect

Asked 2020-Dec-10 at 11:22

I'm trying to transform a pyspark dataframe of size [2734984 rows x 11 columns] to a pandas dataframe calling toPandas(). Whereas it is working totally fine (11 seconds) when using an Azure Databricks Notebook, I run into a java.lang.OutOfMemoryError: Java heap space exception when i run the exact same code using databricks-connect (db-connect version and Databricks Runtime Version match and are both 7.1).

I already increased the spark driver memory (100g) and the maxResultSize (15g). I suppose that the error lies somewhere in databricks-connect because I cannot replicate it using the Notebooks.

Any hint what's going on here?

The error is the following one:

ANSWER

Answered 2020-Dec-10 at 11:22

This is likely because Databricks-connect is executing the toPandas on the client machine which can then run out of memory. You could increase the local driver memory by setting spark.driver.memory in the (local) config file ${spark_home}/conf/spark-defaults.conf where ${spark_home} can be obtained with databricks-connect get-spark-home.

Changing HDF5 compression filter via h5py

Asked 2020-Oct-29 at 14:53

How to read a dataset that is compressed via lzf compression filter and change it to native HDF5 third party filters like szip or zlib? Would simply reading it as shown in How to read HDF5 files in Python, and writing it with compression specified when writing a dataset work?

...

ANSWER

Answered 2020-Oct-29 at 14:53

As @bnaecker said, you can copy the existing dataset and create a new one using a different compression filter. The new dataset can be in the same file or a new one. Note: szip requires special licensing, so I created an example going from lzf to gzip. See example below. The process is the same for any 2 compression filters. Just change compression=value.

Cassandra Windows 10 Access Violation

Asked 2020-Jul-29 at 02:45

EDIT: Although yukim's workaround does work, I found that by downgrading to JDK 8u251 vs 8u261, the sigar lib works correctly.

Windows 10 x64 Pro
Cassandra 3.11.7

NOTE: I have JDK 11.0.7 as my main JDK, so I override JAVA_HOME and PATH in the batch file for Cassandra.

Opened admin prompt and...

java -version

ANSWER

Answered 2020-Jul-29 at 01:05

I think it is sigar-lib that cassandra uses that is causing the problem (especially on the recent JDK8).

It is not necessary to run cassandra, so you can comment out this line from cassandra-env.ps1 in conf directory: https://github.com/apache/cassandra/blob/cassandra-3.11.7/conf/cassandra-env.ps1#L357
