Hello, HBase community,
I have a question about HBase security.
If I want to use wire encryption, I should set kerberos and
hbase.rpc.protection=privacy.
Is there any way not to use kerberos?
(This seems like a silly question.)
(I think... If I could safely provide a key to use for encryption, I

Recently, java.util.regex in the Regex filter (RegexStringComparator) had
been running forever.
It is said that java.util.regex can run forever or stack overflow in the
worst case.
Looking at RegexStringComparator, I saw that two regex implementations
(java, joni) were provided.

I saw that two regex implementations
(java, joni) were provided.
I was wondering if anyone has experience in changing the regex engine
in RegexStringComparator to joni and operating it.
Best Regards,

Hello,
Java regular expression engine is based on backtracking. Thus, a malicious
regular expression may result in a ReDoS (regular expression denial of
service).
When ReDoS occurs in the HBase, the region server's handler is occupied as
a result it cannot process the user's request.
To avoid th
Hello, community
I am creating an in-house library using the HBase client library and
distributing it so that other users can use it.
To prevent conflicts with the user library, we shaded the HBase package.
